"This is my favorite waist shapewear. It's made out of great soft and comfortable material. The material around the waist is thick. and very firm, it really sucks your belly in! It has some boning on the waist top that avoids it to roll down, I have had so many similar shapewear and they all roll down, but this one doesn't roll down at all!!! True to size! if you like it super tight you can even go one size smaller.. Breathable and comfortable enough to be worn for long period of time."
