These spans are awesome. They are the best I've had, and I tried a lot for my wedding last month. Now, I am no connoisseur of spanx, but I can say that they don't always have e magical ability to reshape me that most people talk about. I always feel like I've spent too much money and feel too uncomfortable to have such little change.... But this pair of spanx was different for me. They work!  The only issue is that they will work on your boobs too!  This was no issue for me, as I have no qualms with padding my bra. :)
