Frequently asked questions
How do I measure for a dress shirt?
Neck at the collar line plus a finger's width, and sleeve from the centre of the back of the neck over the shoulder to the wrist bone.
Should I size up for slim fit?
Yes if you're between sizes or have a broad chest — slim cuts run about one inch tighter through the body.
