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.

perfect- just size up

I love this dress and the material, I size up to a large. I am usually a small medium… I have owned a few of their sundresses and they last forever.

Not like description - has shorts

I read and flipped through the photos and assumed it did not have built in shorts. Once received, I was disappointed there are shorts. Also, it's tight on the neck so will be returning

Easy and comfy!

This dress is super comfy. Threw it on while running errands. Love the built in bra and shorts and love that you don’t have to take the whole thing off to use the restroom!

Cute Dress

This dress is very cute, although the halter neck strap bothered my neck, so I sadly had to return it.
