How to Rock a Bump

American Baby: What is your go-to piece now?Jamie-Lynn Sigler: I wear a dress almost every day. In the beginning, I was choosing ones that had an empire waist and some flow, but I quickly realized that fitted is a pregnant woman's best friend. Show off!

AB: Having your first baby is such an exciting time!
JLS: My fiance (baseball player Cutter Dykstra) says his favorite thing is to watch my face when we hear the baby's heartbeat at the doctor's. He's like, "I have never seen you smile any bigger in your whole life."

AB: What other maternity faves have you found?
JLS: The first few months I lived in maternity jeans and leggings. I think they're a great investment. I'm probably going to wear them even when I'm not pregnant. The elastic waists are so comfy!

AB: Does dressing feel different to you now that you're pregnant?
JLS: To be honest, I'm trying not to be self-conscious about it. You should get free passes for all sorts of things when you?re pregnant!
