SPANX

The bold mission of SPANX: to make the world a better place, one butt at a time. For founder Sara Blakely, it all started in 2000 with a bad case of VPL: visible panty lines. She cut the feet off her control-top pantyhose, and a shapewear empire was born. Today these undergarments are wardrobe staples for women and men who trust SPANX to slim their silhouettes and boost their confidence.

So flattering!

I have several of these dresses and I love them. They’re comfortable and super flattering. They wash well and they fit true to size.
