I've been trying to find a good brand of English riding breeches that will fit me really well. I have very skinny and long legs, with a small shape. I'm 5'5 tall, so child's sizes are usually too short on me. Size 26 always fits me around the waist, but every pair of breeches I try on are baggy in the butt and around my knee. I also need the breeches to be a good price, not too expensive. Any suggestions? Thanks.
