SPANX?!

Okay Ladies! I need your help.

I've got a wedding this weekend and was wanting to purchase some sort of spanx to go underneath my dress. Just to keep everything smooth... you know how it is. Lol

So, with that being said...what is the best kind to buy? One that'll do the job and do it well. Without purchasing it and being disappointed in its power.

My dress is long, so I'm not sure if I should do the ones that go all the way to the thigh? Or a corset? Or whatever else they have.

Help!!!

Thanks!! 😁😁
