I have no idea what this type of "clothing" is called but you wear it under your clothing and it is supposed to sort of "suck-in" your stomach. They are not corsets, but have the same sort of effect and I think they are a thinner material. I have only heard of things like this, but never seen any, and have no idea where to look into this. I was wondering if anyone has heard of this, had experience with this sort of clothing, and if you could lead me in the right direction. Thanks!
