Shirt Fits
Fit decides how a shirt sits through the chest, waist and shoulders and whether it looks sharp or relaxed. This hub explains the main shirt fits, so you can choose one that flatters your build. Browse men's shirts (/collections/mens-shirts).

Frequently asked questions
How should a shirt fit at the shoulders?
The shoulder seam should sit right at the edge of your shoulder, where the arm meets the body. If the seam drops onto your upper arm the shirt is too big, and if it pulls across the top the shirt is too small. Shoulders are the hardest part to alter, so get them right first.
What is the difference between slim and tailored fit?
A slim fit is cut close through the chest, waist and sleeves for a sharp, fitted line. A tailored fit is shaped at the waist too but leaves a little more room through the body and arms, so it looks smart without feeling tight, which suits a wider range of builds.
Should I size up for a casual shirt?
For an untucked casual shirt you can size up slightly for an easy, relaxed drape, especially in an overshirt or boxy style. For a shirt you will tuck in or wear under a jacket, stick to your true size so it stays neat through the body.
