I know several guys in barns I go to (dressage and eventing), and they all wear breeches, and look really good (professional). Now in western and trail riding barns I do see jeans most of the time, in english barns most people I know of wear breeches (although there are exceptions of course). I don't think people would even pay an attention if you were wearing jodhpur.
