Landerwood Pilot Shirts These are quite frankly the finest quality pilots shirts I've ever come across. You phone them up with a measuring tape in hand and the man that owns the company will measure you over the phone. You choose the style from their website. The material is exceptional and I have been using them for 8 years buying 6 shirts every 2 years to look my absolute best.
I know they are in the US but they will ship them to you and you wont be dissapointed.
Good luck.
