Mine is exactly the same but with paisley inside the cuff and the check is slightly bigger. Sizes are good in the link, this is the 15.5 collar, I'm normally med/lg in most stuff. Don't know where the arm length measurement is taken from though ?
Bought for a wedding next week but decided I've got a million gingham shirts already, rrp was £125, asking £50, still got the tags on it. Pm me for actual pics as my photobucket account is screwed so can't put em on here.
