For work I wear mens Levis or Wranglers. I love Cruel Girl jeans but sometimes they are in consistant in fit. Some fit perfect, and some don't, even within the same size, cut and style.
I love the Cowgirl Tuff jeans for riding but they do stretch, keep that in mind if you don't like a saggy butt.
All my Miss Me's have a ton of stones on the the back pockets so I just wear them to town, not riding.
I have some Akdicted jeans, I love them for work, going to town and riding so far, not as cool as the Miss Me's but they fit me better.
I haven't tried the the QBaby jeans because I never had any luck fitting into "girl" Wranglers, hence using the mens Wranglers for work!
I have ordered some jeans from Alloy, Standards & Practices, I think, the boyfriend cut. Love them! They fit snug in the rear have plenty of leg and boot room, with a little bit of stretch. I LOVe to ride in them and they are cheap.
