A practical customer guide for choosing the right neckline, fit and size.
Regular Fit Crew Neck T-Shirt
A regular fit crew neck T-shirt is the classic everyday option. It has a rounded neckline and a comfortable straight fit through the chest, waist and body.
How a regular fit crew neck fits
Regular fit T-shirts should sit neatly on the shoulders without pulling across the chest. The body should feel comfortable rather than tight, with enough room to move naturally.
Best for
- Everyday wear
- Layering under hoodies, overshirts and jackets
- Men who prefer a classic comfortable shape
- Casual outfits with jeans, joggers or shorts
- Multipack T-shirts and daily essentials
Fit feel
- Comfortable through the chest
- Straight through the body
- Not too tight and not oversized
- Easy to wear all day
- Classic neckline that works for most men
Choose a regular fit crew neck if you want a simple, reliable T-shirt that works as an everyday essential and layers easily with the rest of your wardrobe.
Slim Fit Crew Neck T-Shirt
A slim fit crew neck T-shirt has the same classic rounded neckline, but the body is cut closer through the chest, sleeves and waist.
How a slim fit crew neck fits
Slim fit T-shirts should follow the shape of the body without feeling restrictive. The sleeves usually sit closer on the upper arm, and the waist is more tapered than a regular fit.
Best for
- A sharper, more modern look
- Wearing under jackets or overshirts
- Men who prefer a closer fit
- Smart casual outfits
- Layering without excess fabric
Fit feel
- Closer through the chest
- Neater around the waist
- More fitted sleeves
- Less loose fabric
- Modern streamlined shape
If you are between sizes or prefer more room, consider sizing up in slim fit styles. Slim fit should look neat, but it should not pull tightly across the chest or stomach.
Regular Fit V-Neck T-Shirt
A regular fit V-neck T-shirt has a V-shaped neckline with a comfortable body fit. It offers a slightly more open neckline compared with a crew neck.
How a regular fit V-neck fits
A regular fit V-neck should sit comfortably through the shoulders, chest and waist. The neckline should sit cleanly without stretching or gaping.
Best for
- Layering under open shirts
- Wearing under knitwear or jumpers
- Men who prefer a more open neckline
- Casual and smart casual outfits
- Warmer weather and relaxed everyday wear
Fit feel
- Comfortable regular body fit
- Open V-shaped neckline
- Easy to layer
- Classic but slightly sharper than a crew neck
- Good balance of comfort and shape
Choose a regular fit V-neck if you like a more open neckline but still want the comfort and room of a regular fit T-shirt.
Slim Fit V-Neck T-Shirt
A slim fit V-neck T-shirt combines a closer body fit with a V-shaped neckline. It is a good option for a clean, modern look with less fabric around the body.
How a slim fit V-neck fits
Slim fit V-necks should sit closer through the chest, sleeves and waist. The neckline should look clean and structured, while the body fit should remain comfortable enough for movement.
Best for
- Modern everyday styling
- Layering under shirts and jackets
- Men who prefer a sharper silhouette
- Smart casual outfits
- Wearing with jeans, chinos or tailored casual trousers
Fit feel
- Closer body shape
- Open V-neckline
- Neater sleeves
- Less excess fabric
- More fitted through the waist
If the fabric pulls across the chest, stomach or shoulders, the size may be too small. A slim fit should be close, not uncomfortable.
Tank Top / Vest
A tank top, also known as a vest, is a sleeveless top designed for lightweight comfort, layering or warmer weather.
How a tank top fits
Tank tops should sit comfortably around the chest and shoulders without cutting too tightly under the arms. The body can be regular or slim depending on the style.
Best for
- Warm weather
- Layering under shirts
- Loungewear and casual comfort
- Gym or active use depending on fabric
- Men who prefer a sleeveless shape
Fit feel
- Sleeveless and lightweight
- More freedom around the arms
- Comfortable for layering
- Cooler than standard T-shirts
- Easy casual fit
Choose a tank top if you want a sleeveless option for layering, lounging, warm weather or active days.

How to Measure for a T-Shirt
Measure around the fullest part of your chest, keeping the tape measure level and comfortable. Do not pull the tape too tight.
You can also measure a T-shirt you already like. Lay it flat, measure across the chest from armpit to armpit, then double the number to estimate the full chest measurement.
How Should a T-Shirt Fit?
- The shoulder seam should sit close to the edge of your shoulder.
- The chest should feel comfortable without pulling.
- The sleeves should sit neatly around the upper arm.
- The body should fall naturally without clinging too tightly.
- The length should usually sit around the top to middle of the hips.
Fabric & Fit Notes
- Cotton T-shirts are soft, breathable and ideal for everyday wear.
- Cotton stretch T-shirts offer extra movement and a closer fit.
- Modal or lyocell blends can feel smoother and softer against the skin.
- Performance fabrics may feel lighter and better for active use.
- Heavier cotton can give a more structured premium feel.
