I am 5'5", 156lb pre-pregnancy, 162lb currently at 25w3d. I bought a medium based on the reviews and it was the right size choice. No one seems to have posted a picture of only these being worn so I will!
Quality wise it is very stretchy and the fabric is soft. It feels like it will breathe fairly well in the summer. Stitching looks good. The picture is of me stretching it pretty tight.
Baby has given me some cellulite on my butt and thighs and I'd say it does a pretty fair job of smoothing it out. Not perfect, but good enough for me. It does not squish my booty which I appreciate. These will save me from chub rub for sure. What I really love is the support band that goes from one side, down around my belly, and to the other side. You can see it very well in the photo. That support feels soooo good especially now that baby is packing on the weight. Happy I bought these for sure and may get another pair since I wear a lot of dresses in the summer.
