Find Your Perfect Tee Fit in Five Steps
A perfectly fitting tee is the foundation of every wardrobe. Here's exactly what to measure, where to look, and how to know when you've found the one.
5 min read · IrisThe tee is fashion's most honest garment. There's nowhere to hide in a basic cotton crew—which is precisely why fit matters so much. A tee that's even slightly off can overwhelm your frame, bunch awkwardly, or simply feel wrong against your skin. The good news: finding your perfect fit doesn't require a tailor or a degree in pattern-making. It requires knowing exactly where to look.
This guide walks you through the five key fit points every woman should check before buying. Whether you're shopping in-store or online, these measurements and visual cues will help you spot a tee that actually works for your body—not against it.
A tee that fits well at the shoulders will hang correctly everywhere else.

Step one · 2 minutes
Check the shoulder seam placement
The shoulder seam should sit exactly where your shoulder ends—not creeping up your neck or sliding down your arm. Raise your arm to a 90-degree angle; the seam should stay put without bunching or gaping. This is the single most important fit point because everything else depends on it. If the shoulders are wrong, no amount of tucking or layering will fix it. Stand in front of a mirror and look at your profile to verify the seam aligns with your natural shoulder point.
If you're between sizes, the smaller size usually fits better in the shoulders. You can always size up in length elsewhere.

Measure sleeve length to your wrist
Sleeves should end between your wrist bone and the base of your thumb—roughly where your arm naturally ends when relaxed at your side. If sleeves hit mid-forearm, the tee is too short. If they cover your hand, it's too long. This matters both aesthetically and practically: short sleeves can make your arms look stubby, while long sleeves bunch and feel sloppy. Wear the tee as you normally would (not stretched or tugged) and check the length in a mirror.
If you have longer arms, look for 'tall' or 'extended' sizing options rather than rolling cuffs, which creates bulk.
Step three · 2 minutes
Test the torso drape and hem length
The tee should skim your torso without clinging or billowing. Raise your arms; the hem should stay at or just below your hip bone, not ride up to your ribs or hang past mid-thigh. A tee that's too long looks shapeless; one that's too short exposes your midriff when you move. The fabric should have a slight give—you should be able to pinch about an inch of material at your side without feeling tight. This is where body type matters most: pear-shaped frames often need a bit more length, while petite frames benefit from cropped or standard lengths.
If a tee is perfect everywhere except length, a tailor can hem it for $10–15. Shoulder seams and sleeve length cannot be easily altered.

Verify neckline placement and comfort
The neckline should sit at the base of your neck without gaping or pulling. For a crew neck, you should be able to fit one finger comfortably inside the collar when it's fastened (or resting naturally for crewnecks). If the neckline is too tight, it will create an unflattering pucker; too loose, and it looks sloppy and ages you. Move your head side to side and forward; the neckline should stay in place. Pay attention to how the neck opening frames your face—some women prefer a slightly higher crew, others a lower scoop.
Neckline preference is deeply personal. Try on multiple styles (crew, v-neck, scoop) to see what feels and looks best on your frame.
Step five · 2 minutes
Walk, sit, and reach in the tee
A tee that fits standing still might twist, ride up, or bunch when you move. Walk around the fitting room or your home for at least 30 seconds. Sit down and notice if the hem rides up uncomfortably or if the shoulders pull. Reach overhead and check that the hem doesn't expose your midriff. Bend forward slightly. These real-world movements reveal fit issues that static mirror-checking misses. If anything feels restrictive, bunches, or moves with you rather than staying in place, it's not the right fit.
Online shoppers: order two sizes and do a full movement test at home before deciding. Return the one that doesn't perform.
How to know it works.
A perfectly fitting tee should feel invisible—supportive without being tight, present without being fussy. You should forget you're wearing it within minutes. The fit should work with your body, not against it, and should require zero adjustments throughout the day.
Questions at the mirror.
What if I'm between sizes?
Go with the smaller size if the shoulders fit perfectly. You can layer or size up in length, but wrong shoulders cannot be fixed. If both sizes gap at the shoulders, that brand may not be cut for your frame.
Does fabric type affect fit?
Yes. Heavier cottons hold their shape better; lightweight or stretchy fabrics may cling or bag over time. Check the fiber content and read reviews about how each fabric behaves after washing. A 100% cotton tee will fit differently than a cotton-elastane blend.
Should I size down for a fitted look?
No. A fitted tee should still allow about one inch of pinch room at the side seam. Sizing down creates pulling, restricts movement, and looks uncomfortable. 'Fitted' is a cut, not a size.
How do I account for shrinkage?
Check the care label. If the tee is 100% cotton and machine-washable, assume 3–5% shrinkage. Some brands pre-shrink; others don't. When in doubt, size up slightly or air-dry to minimize shrinkage.
What's the difference between petite and regular sizing?
Petite sizing shortens the torso length, sleeve length, and overall hem—not just the hem. If you're under 5'4", petite sizing often fits better than regular sizing hemmed short. Try both to see what works for your proportions.
