Im 7 months pregnant and this dress fits beautifully over my bump. I bought it for all of the Go Red events Im attending for National Heart Month, but I may not keep it because the fabric does seem to wrinkle easily, and it may not be ideal for wearing under a big winter coat. The fabric is a stiff polyester, a bit like table cloth fabric, but not truly offensive. It does breathe, and the dress is really cute and flattering! Im 55, 143lbs and a 34DD. The small is awesome, and its a true bright red!
