I like lululemon. It is actually yoga/pilates clothes, but they fit well and can double as sweats. Much better quality (and much more flattering!) than Juicy. I don't mind venturing out in them. You can't order them online, but they do phone orders. They have a website that shows the styles though. The reverse groove pants are really flattering.
I agree! lululemon is super flattering, i wear their pants all the time.
