Should order a size smaller.
My pregnancies left with severe diastasis recti, and although I lost all the weight, my abdomen is a problem area. I ordered a small, which is my size, and this shaper smooths everything, but I don't feel much compression. You know how these "give in" after wearing them for several times, I also think that the booty part goes way up. Like another reviewer mentioned.
I will buy extra small.
