Clothing measurements
Collar size
The neck measurement used to size dress shirts, in inches (US and UK) or centimetres (EU).
Dress shirts are sized by the collar: the circumference of the buttoned collar. A 15.5 inch collar is about a 39 cm collar.
To find your collar size, measure around the base of your neck where the collar sits, keeping one finger between the tape and your neck for comfort.
