Frank Thomas is an ENglish brand, they're generally cut to fit taller/thinner riders. (As are most brands manufactured mostly in europe)
Check out the WERA Forums for used stuff cheap! forums.13x.com I got a brand new set of Teknic Violator leathers for $225 shipped.

Sometimes you can even find a set of cusotm leathers on there, plus if they have scuffs it adds cred!
