They are not Lululemon which is a major plus :) I never had a problem with quality like others has said. I have Lucy pants that are at least 2 years old, worn several times a week and they are still holding up.
I just wish they were a bit more trendy. Lots of basics and "safe" colors but sometimes you want something a bit more out there.
Customer service is good even though at times a bit annoying when they ask you if you need help every 3 minutes :)
