I normally wear medium and got a small (I'm 5'5 and 135 pounds pre-pregnancy). It fits nicely now, but it might feel a bit tight in the third trimester (I still think it will work because of the stretch). So I think I could have gotten small or medium and been okay.The material is very nice and soft and the dress appears to be well constructed. It's very flattering and I love the pockets. The mauve color is pretty but the color looks different depending on the lighting. I haven't washed it yet so we'll have to see how it holds up, but I usually wash sweater dresses on gentle cycle and in a mesh bag (and no tumble dry) so that should help. I would love to buy this dress again in other colors and maybe get a medium just to have more room for later in pregnancy. This dress makes me feel so pretty. I love it.Also—other reviews mentioned the material being scratchy. I don't find this true other than possibly the seam on the elastic gathered waist. I always wear a shirt under my dresses, so that seam isn't directly against my skin. But if you wear it right against your skin then I could see how that seam could be a bit scratchy. The sweater material itself is very soft and comfortable.
