So, I just received in the mail and wanted to leave a thorough review. But I will try to use my body type as a guide. Pear-Shaped

I bought this purposely for the thigh slimming aspect and not so much for the corset/waist cinched. I am bottom heavy and was informed that helps tighten the skin (body changes after birth)

Sizing:  WAY OFF. I typically am a size XSmall/Small in the US... Size 26 in Levis jeans or Size 0-2 at Banana Republic.
I bought the Manufacturer Large I am a USA SM/XS

MATERIAL: Very stretchy and breathable. I didn't think it would fit, but with some wiggling- I made it in.
 May be itchy for some but not me. It does smell like plastic but after a few moments it goes away (or I got used to it ...)
I am pretty sure this corset won't last very long but for the price, you cant go wrong. Its tight enough to do the trick but still let you breath.

Shape/Functionality: well thought out. I hadnt seen one like this and actually it may be my favorite. Its a one piece but functions as two. The shorts slide on and then you tighten the corset. Ive seen them where you have slide your butt through a corset piece and then button the additional clincher. This was a lot better.

CONS: minor cosmetic deficiencies but nothing to cry about loose string and plastic fabric.
And, I wish the shorts were like capris and ended at the calf and not cutoff on top of the knees. It kind has that sausage muffin-top effect with jeans on.
Again- this is a review from a bottom heavy girl. Ive seen girdles  have that affect with top heavy girls on their love handles... we cant win them all
