I am so happy with this purchase!  It's comfortable enough to wear all day, and I'm in no rush to get out of it at the end of the day. The material is light but has great firming power.  They especially did a great job with the legs - they extend seamlessly and come to an end without leaving a roll or line at the bottom.  Through slacks, I literally cannot feel where they end.

I bought one to try, and I just bought 3 more!
