You’re standing in front of a rack of t-shirts. Maybe you’re a founder who just got funding, or a designer who finally scraped together enough for your first run. You think you know what a t-shirt is.
Let me stop you right there.
A t-shirt isn’t just cotton and thread. It’s physics. It’s chemistry. It’s psychology—because people wear them like armor, like identity, like rebellion. And if you don’t get the details right? Your brand dies by returns, pilling, and one-star rants about “cheap feel.”
I’ve spent 14 years knee-deep in dye vats, arguing with fabric mills at midnight, and pulling apart seams under factory lights to see why they split after two washes. I’ve seen brands blow $80K on a launch because someone picked the wrong neckband. I’ve watched buyers cry when their “soft” crewnecks came back stiffer than denim.
So this isn’t some glossy guide from a marketing team that’s never touched a sewing machine. This is raw. Messy. Real.
We’re going deep on t-shirt types—but not all of them. Not every damn sleeve style gets equal time. We’ll focus on what matters: necklines and fits, because those are where most new brands fail. The rest? Mentioned, sure. But we’re not wasting energy on puff sleeves when your core product can’t survive a gym session.
And yeah—this list is based on something called Lezhou Garment’s old visual guide. Found it buried in a PDF folder last year. Good bones. Bad execution. They listed everything but told you nothing about what actually works on the floor.
So let’s fix that.
At Fexwear, our job isn’t to make pretty catalogs. It’s to keep your order from turning into landfill. We’ve been doing private-label sportswear since 2010 out of Wuhan, helping startups, Shopify sellers, even ex-tech bros who decided athleisure was “passive income.” Some made it. Most didn’t.
Here’s why—and how to avoid being one of them.
Crew Neck T-Shirt – The Silent Killer of New Brands
If I had a dollar for every brand that launched with a “basic crew neck” and went under six months later…
Look. The crew neck is the default. The safe choice. The trap.
It looks simple: round collar, sits above the collarbone. Everyone wears it. So you assume it’s easy to produce.
Wrong.
The devil’s in the rib knit. That band around the neck? If it’s too tight, it cuts off circulation. Too loose, and it flares after three washes. Get the stitch count wrong, and it rolls. Use cheap elastane, and it loses recovery in storage.
One client—let’s call him Mark—ordered 5,000 units of organic cotton crewnecks. MOQ met. Price looked good. He skipped the pre-production sample check because he was “in a rush.” Shipment arrived. First thing he noticed?
The neckbands were twisted.
Not crooked. Twisted. Like someone had spun them 90 degrees before stitching.
Turns out the factory used leftover ribbing from a polo shirt run. Different tension. Different cut. No one caught it until packing.
Mark lost $23K in unsellable stock. And that was before customer complaints about sagging necklines started rolling in.
Here’s what you need to know:
- Rib knit should be 1×1 or 2×2, depending on weight.
- Elastane content must be 3–5% minimum for recovery. Less than that? Say goodbye to shape after wash #3.
- Neck tape matters. At Fexwear, we use self-fabric or cotton-linen tape on almost every crew neck we produce—it stabilizes the seam, prevents stretching, and stops that dreaded “gaping” when someone raises their arms.
Oh, and don’t trust “organic cotton” labels without verification. We ran a batch last summer using GOTS-certified yarn—great on paper. But the mill hadn’t cleaned its dye tanks in months. Cross-contamination. Failed OEKO-TEX test. Whole roll scrapped.
That’s why we do mid-line audits. That’s why we pull random samples and stretch them hard.
You want softness? Fine. But softness without structure is garbage.
And yes, we source the fabric, develop the pattern, handle production—all through our network of vetted factories. You can see our full range of activewear-ready basics in the catalog — but don’t just pick what looks nice. Ask questions.
Like: What’s the GSM? What’s the shrinkage rate? Did you test stretch recovery?
Because if you don’t, your customers will.
V-Neck T-Shirt – Flattering Until It Falls Apart
V-necks sell. They photograph well. They make short guys look taller, round faces look leaner.
But here’s the dirty secret: V-necks are structurally unstable.
That diagonal seam? It’s a stress point. Every time someone pulls the shirt over their head, that seam takes the hit. If the joining method is weak, it splits. If the fabric lacks recovery, it widens into a gaping canyon.
I saw a brand—premium pricing, Instagram-heavy—get roasted online because their $48 V-necks looked like boat necks after two wears.
Why?
They used a single needle chainstitch. Cheap. Fast. Fragile.
At Fexwear, we mandate double-needle flatlock + bar tack reinforcement at the apex of the V. Takes longer. Costs more. Prevents disaster.
Also: symmetry. You’d be shocked how many factories let the V drift left or right. Half a centimeter doesn’t sound like much—until you’re holding two shirts side by side and one looks “off.”
We had a QC slip-up in 2022. Batch of 3,000 V-necks. All passed initial inspection. Then a buyer did a lay-flat photo shoot. Noticed 17% had asymmetrical Vs.
Traced it back to a misaligned jig in cutting. Fixed it. But we ate the cost of remaking 500 units.
Lesson: always do a lay-flat check on V-necks. Not just on mannequins.
And don’t ignore fabric drape. A stiff blend might hold its shape, but it won’t flatter. We tested 14 different 60/40 cotton-poly blends last quarter—only three had the drape we wanted for V-necks. The rest looked like cardboard.
Pro tip: if you’re doing sublimation prints on V-necks, align the pattern across the seam. Otherwise, you get a design split down the middle like a bad Photoshop job.
Yeah, we’ve done that. Fixed it. Now it’s standard.
Scoop Neck T-Shirt – The “Soft Girl” Trap
Scoop necks? Popular. Especially in women’s activewear. Exposes collarbones. Breathable. Feminine.
But here’s the problem: they expose flaws faster than any other neckline.
Too wide? Looks sloppy. Too narrow? Chafes. Fabric too thin? See-through in sunlight. Too thick? Suffocating.
And recovery? Forget it. Most scoop necks lose tension within five washes unless you engineer them properly.
We had a yoga brand come to us last year. Wanted a “buttery soft” scoop neck tank. Used Tencel/modal blend—luxurious, sustainable, perfect on paper.
First wash test: 12% elongation at the neckline. Second wash: 19%. By wash five? The neck stretched so far it looked like an off-shoulder.
Why?
No stabilizing tape. No reinforced stitching. Just beautiful fabric… failing structurally.
We redesigned it: added a hidden elasticized tape inside the seam, switched to a finer-gauge rib (not traditional rib, but a textured performance knit), and increased stitch density by 20%.
Cost went up 8%. Returns dropped from 14% to under 3%.
Moral: sustainability means nothing if the garment doesn’t last.
And don’t get me started on dye lot consistency. Tencel takes dye differently than cotton. One batch slightly darker? On a wide scoop neck, it’s glaring.
Always request shade banding tests—unroll three yards continuously and check for color shifts. We caught a batch last month where the first 50 yards were perfect, the next 200 faded. Saved a client from disaster.

Not marketing fluff. Lab numbers.
Henley T-Shirt – The “Casual Smart” Minefield
Henleys are tricky. They walk the line between casual and put-together. Three-button? Five-button? Raglan sleeves? Long sleeve? Short?
But the real issue?
Button alignment.
I’ve seen factories slap buttons on with zero spacing consistency. Off by 2mm? Looks amateur. 5mm? Unwearable.
And thread strength? If you use polyester thread on cotton fabric, it can pop during washing. Cotton-on-cotton is better—but slower, pricier.
One client insisted on mother-of-pearl buttons for “premium feel.” Great idea. Until we tested wash durability.
After 10 cycles: 30% of buttons cracked. Why? Natural material, uneven thickness, no flexibility.
Switched to corozo—plant-based, durable, looks identical. Zero failures in 30-wash test.
Also: placket width. Too narrow, and the buttons strain. Too wide, and it flaps open.
Our standard? 1.8 inches. Tested across 8 body types. Holds shape. Lies flat.
And don’t forget the neckband. Henleys need extra stability because of the button stress. We use interlining tape on every unit—adds cost, but prevents warping.
MOQ for a proper Henley run? Minimum 1,000 pcs. Less than that, and factories won’t bother with custom plackets or button molds.
We can help. We’ve done micro-batches as low as 300 with adjusted pricing. But you pay for the precision.
Polo Shirts – Where “Formal” Meets Factory Reality
Polo shirts aren’t t-shirts. They’re hybrids. Collars. Plackets. Buttons. Ribbed cuffs.
And oh god, the collars.
A bad polo collar curls. Or stands straight up like a duck’s tail. Or stretches out and never recovers.
We once had a client demand “crisp, structured collars” for a golf line. Factory used heavy interlining. Looked sharp in photos.
Worn in 90°F heat? Stiff as cardboard. People took them off after 20 minutes.
Redesigned with lightweight fusible + moisture-wicking underside. Comfortable. Held shape. Sold out in 3 weeks.
Buttons? Two-ply reinforced shank. No exceptions.
Stitching? Minimum 12 SPI (stitches per inch) on collar edges. Lower than that, and it peels.
And sizing—polos run small. Always. Because of the structured fit. We now include a fit disclaimer in packaging for every polo we produce: “Runs small. Consider sizing up.”
Saved one brand from 22% return rate due to “too tight.”
MOQ for polos? 1,500 units minimum if you want custom collar molds and placket finishes. Less than that, you get generic patterns.
But we’ve done 800-unit runs with shared tooling. Slower, but possible.
If you’re building a pro-level line, polos matter. Check our Teamwear section in the catalog —we’ve got performance polos with UV protection, anti-odor tech, and breathable mesh backs.
Not your dad’s golf shirt.
Mock Neck (High Neck) T-Shirt – The “Athleisure Tax”
Mock necks are everywhere now. Supposedly “elevated.” “minimalist.” “technical.”
Bullshit.
Most mock necks are just tall ribbed bands glued onto basic tees. No engineering. No thought.
Result? They ride up. They constrict. They lose elasticity.
Real mock necks—like the ones we make for premium yoga and training lines—have:
- Double-layer construction
- Elastane-reinforced rib (minimum 5%)
- Flatlock stitching to prevent chafing
- Height calibrated to 3.5–4 inches (anything higher restricts neck movement)
We had a client who wanted a “high-fashion” 6-inch mock neck. Model looked great. Real person wearing it during a workout?
Couldn’t turn their head.
Back to the drawing board.
Also: temperature regulation. Thick mock necks trap heat. We now use mesh-lined versions for high-intensity lines. Lets skin breathe. Looks clean.
And don’t skip the stretch recovery test. Pull the neck to 150% of its size. Let go. Should return to original shape in under 5 seconds.
If not? Reject it.
We did. Twice last year.
Cowl Neck, Boat Neck, Off-Shoulder – The Women’s Line Gamble
These are style-driven. Not functional. Not durable.
Cowl necks drape. Boat necks expose shoulders. Off-shoulder? 1980s nostalgia.
But they’re fragile.
Cowl necks require ultra-stretch, recovery-rich fabrics—think 88/12 poly-spandex with mechanical stretch. Anything less, and the drape collapses.
Boat necks? High risk of seam slippage. Shoulder seams must be triple-stitched and reinforced with tape.
Off-shoulder? Even worse. Elastic degrades fast. We tested seven different elastic types—only one lasted 20+ washes without losing tension.
And fit? These styles are unforgiving. One client had a 28% return rate on cowl-neck tops because “they fell off my shoulders.”
Turns out the shoulder seam was set 1.5cm too far forward.
Fixed the pattern. Returns dropped to 9%.
Lesson: women’s cuts aren’t just smaller versions of men’s. They need graded darting, curved seams, and mobility testing.
We do live-fit sessions with models before approving any run over 1,000 units.
Not optional. Necessary.
Sleeve & Fit Deep Dive – Where Comfort Meets Catastrophe
Alright. Let’s shift gears.
We’ve covered necks. Now: fits.
Because no one cares about your “signature V-neck” if the shirt fits like a sack.
Regular Fit – The “Safe” Lie
“Regular fit” means nothing.
One brand’s regular is another’s oversized.
At Fexwear, we define regular fit as:
- Body length: Hip-grazing
- Chest ease: 4–6 inches over body measurement
- Sleeve cap: Moderate rise, not tight
But here’s the catch: regular fit sells only if the fabric has memory.
We had a budget brand insist on 100% cotton. “Natural feel,” they said.
After one season: pilled, shrunk, stretched out.
Switched to 92/8 poly-spandex. Same look. Better recovery. Returns cut in half.
Slim Fit – The Ego Trap
Slim fit = “I work out” energy.
But if the armhole is too tight? Rubs underarms raw.
If the chest is too snug? Can’t raise arms.
We measure bi-swing allowance on every slim-fit pattern. Minimum 18° freedom of movement.
One client ignored it. Got 17 negative reviews: “Can’t lift my arms in this.”
Redid the block. Added gussets. Fixed.
Athletic Fit – The Gold Standard
This is what most people want, even if they don’t admit it.
- Room in shoulders
- Snug through waist
- Slightly tapered sleeve
We use 3D body scans to calibrate athletic fit blocks. Adjust for posture, muscle mass, torso length.
Case study: cycling jersey line. Needed aerodynamic but comfortable.
Tested three prototypes. Final version had strategic laser-cut perforations under arms, silicone grip at hem, and 80/20 recycled poly-spandex blend.
Passed wind tunnel tests. Wore it myself for 8 hours straight. No chafing. No slippage.
That’s how you build trust.
Relaxed & Oversized – The Streetwear Hustle
Oversized is hot. But oversized ≠ poorly made.
Loose fabric sags. Sleeves droop. Hems twist.
Solution? Weighted hems and reinforced side seams.
We use 2.5mm twin-needle stitching on all oversized bottoms. Prevents rips.
And fabric choice? Heavy single-jersey or french terry. Light stuff turns into rags.
MOQ for oversized runs? 1,200 min. Factories hate the extra fabric waste.
But we optimize layout. Reduce waste by 18% on average.
Wrapping Up
Alright, I’ve got to get back to chasing a dye-lot issue. That’s enough for now.
FAQs
What material is similar to silk?
Tencel or high-filament polyester. But don’t just copy “silk-like”—test drape and friction. We saw two factories deliver “silk-touch” fabric that felt like plastic wrap after washing.
Which fabric creates a formal appearance?
Polo shirts with structured collars and fine gauge piqué. But only if stitching is flawless. One misaligned button kills the vibe.
What is the most durable fabric?
88/12 recycled polyester-spandex. Survived 70+ washes in our lab last quarter. Outperformed nylon and cotton blends.
Best fabric for moisture wicking?
Polyester with capillary channels. Not all poly is equal. We test RET values—anything above 18 fails.
Cotton vs. Organic Cotton?
Organic avoids pesticides, but still shrinks. We pre-shrink all organic cotton at Fexwear. Non-negotiable.
How do I avoid neckband twisting?
Demand neck tape + correct ribbing cut direction. We caught this in a mid-line audit in 2023—saved 3,000 units.
