I am newly pregnant and my 34C Breasts are growing and so tender and sore. I bought this to wear under pajamas in a size medium. It feels like a hug for my boobs. Not constrictive and supportive like a sports bra but just perfect for laying on the couch or doing chores around the house. Highly recommend. It does come with a funky moth-ball smell but two washes and its totally gone now.
