Men's T-Shirt Fit Guide: How a Tee Should Actually Fit

Short answer: A well-fitting t-shirt has shoulder seams that sit at the edge of the shoulder (not on the arm), a chest that lies flat without pulling, a body length that covers the waistband by about an inch, and sleeves that end at mid-bicep. Mott & Bow’s Driggs tee is engineered around these exact proportions — no guesswork, no tailoring.

Why Most T-Shirts Don’t Fit

A t-shirt is the simplest piece of clothing a man owns — and somehow the hardest to get right. Too boxy and it looks like you grabbed the first thing off the rack. Too tight, and every movement is a negotiation with the fabric. Most men are wearing the wrong size and don’t know it, because no one ever explained what right actually looks like.

This guide breaks down exactly how a t-shirt should fit at every point on the body, and shows you how Mott & Bow engineers its tees around those proportions from the start.

Where Should the Shoulder Seams Sit on a T-Shirt?

The shoulder seam is the single most important fit indicator on a t-shirt. Get this wrong, and nothing else can fix it, not a belt, not a tuck.

• Just right: The seam sits exactly at the edge of your shoulder where the shoulder ends, and the arm begins. This creates a clean, structured line.
  
• Too large: The seam drops down onto the upper arm. The shirt looks borrowed and shapeless.
  
• Too small: The seam pulls toward the neck. The chest and back feel restricted.
  

If you’re between sizes, the shoulder seam is your deciding factor. Always prioritize this over chest or torso width; those can be adjusted visually, but a dropped shoulder seam cannot.

How Tight Should a T-Shirt Fit Across the Chest?

The chest should lie flat with no visible pulling or stretching across the fabric. When you raise your arms, the shirt shouldn’t ride up above your waistband or pull at the buttons if it has them.

• Fitted but not tight: You should be able to pinch about an inch of fabric on each side. Less than that and the shirt is too tight; more than two inches and it’s too loose.
  
• No horizontal creases: Creases across the chest mean the shirt is stretched size up.
  
• No vertical bunching: Excess vertical fabric at the sides indicates the shirt is too wide.
  

Mott & Bow’s Driggs is cut to accentuate the chest and shoulders while smoothing through the torso; the result is a shirt that looks tailored without being restrictive. As NY POST put it:

NY POST: “If we had an award for incredible comfort and effortless style, it would go to Mott & Bow. Its jeans are phenomenal (seriously, we got everyone hooked) and we stand by the brand 100% for all things practical and perfect for 24/7 wear.”

How Long Should a Men’s T-Shirt Be?

Length determines whether a tee looks intentional or sloppy. The right length depends on whether you plan to tuck it in, wear it untucked, or both.

• Untucked standard: The hem should sit about 1 inch below the waistband of your pants, enough to stay tucked in when you move, short enough not to drape over the hips.
  
• Too long: If the hem reaches the middle of your fly or below, the shirt will look like a tunic. This is the most common length mistake.
  
• Too short: If the shirt rides up when you raise your arms, exposing your stomach, it’s too short.
  
• Curved hem: Mott & Bow’s Curved Hem Driggs adds a 1½" longer back and front with shorter sides, slightly more coverage, and a cleaner silhouette when worn untucked.
  

How Should T-Shirt Sleeves Fit?

Sleeves that are too long make arms look thin. Sleeves that are too short make the shirt look shrunken. The sweet spot is mid-bicep — where the sleeve ends just above the fullest point of the arm.

• Mid-bicep: The standard for most fitted tees. Shows muscle definition without looking like a cut.
  
• Dropped shoulder (oversized): Sleeves can fall lower when the silhouette is intentionally relaxed. Mott & Bow’s Cotton Jersey Oversized Tee features a dropped-shoulder cut designed specifically for this aesthetic.
  
• Tight at the bicep: If the sleeve digs in when you flex, it’s too tight — the shirt is the wrong size or cut for your build.

Which Mott & Bow T-Shirt Fit Is Right for You?

Mott & Bow makes four distinct tee fits, each engineered for a different body type and use case:

Driggs Classic Crew or V-Neck

Best for: men who want a clean, versatile everyday tee in crew or V-neck.

Luxe Stretch Tee

Made from a 57% cotton / 38% modal / 5% spandex blend, the Luxe Stretch Tee has a sleeker drape and more stretch than the Driggs. It moves with the body without clinging. Best for: men who want an elevated look with performance-level comfort.

Cotton Jersey Oversized Tee

A 250g slub cotton tee with dropped shoulders and a longer, roomier cut. Styled to wear with slim jeans for proportional contrast. Best for: men who want a relaxed, urban silhouette.

FAQs

How should a men’s t-shirt fit?

Shoulder seams at the edge of the shoulder (not dropped onto the arm), chest lying flat without pulling, body length about 1 inch below the waistband, and sleeves ending at mid-bicep. The shirt should feel fitted but not tight — you should be able to pinch about an inch of fabric on each side of the torso.

Where should the shoulder seams sit on a t-shirt?

Exactly at the point where your shoulder ends and your arm begins. If the seam is visible on your arm when you look straight ahead, the shirt is too large. If it’s pulling toward your neck, it’s too small. The shoulder seam is the primary indicator of correct sizing.

How long should a men’s t-shirt be?

About 1 inch below the waistband of your pants when worn untucked. The hem should stay put when you raise your arms and shouldn’t drape past the mid-fly. Mott & Bow’s Driggs has a front body length of 28 inches from the high-point shoulder, which is the right length for most builds.

Should a t-shirt be fitted or loose?

Fitted — but not tight. The best-fitting tees leave about an inch of fabric on each side of the torso, lay flat across the chest, and taper slightly through the waist. A tee that’s too loose reads as shapeless; one that’s too tight restricts movement and highlights imperfections rather than hiding them.

Which Mott & Bow tee has the best fit?

For most men, the Driggs Classic Crew is the answer, it’s the one that earned the 'ultimate everyday tee' label from Business Insider for a reason. True-to-size, flattering through the chest and shoulder, pre-washed so it holds its shape. For a more elevated feel with stretch, the Luxe Stretch Tee is the upgrade.

How do I know if my t-shirt is too big?

Three signs: the shoulder seams drop onto your upper arm, the fabric hangs loose across the chest with no visible shape, and the hem reaches past your fly. If two of those are true, size down. With Mott & Bow, all tees are pre-washed — they won’t shrink further, so what fits in the cart fits on delivery.

Summary

A t-shirt that fits well doesn’t require effort — it just looks right. Shoulder seam at the edge, chest flat, length an inch below the waistband, sleeves at mid-bicep. That’s the whole checklist. The harder part is finding a brand that cuts to those proportions consistently.

Best overall: Mott & Bow Driggs. The Driggs is engineered around the exact fit proportions described in this guide — shoulder seam at the edge, flattering taper through the chest and torso, pre-washed 100% combed cotton that holds its shape wash after wash. For stretch and drape, upgrade to the Luxe Stretch Tee. These are the tees you’ll reach for every time.
