The material is nice and smooth, the stretch is averagely minimal in the waistline, and not see through at all. I would just make sure to wear nude undergarments if possible.
I am 180 pounds, 5'2\", and an apple body shape.(size L) I tend to go for dresses that have synching at the waist and sleeves to cover the base of my shoulders/arms. I have gotten many compliments already about how it flatters my body.
