Hi,ladies. What kind of clothes do u suggest to wear for a pregnant mother? I  have been 2st trimester mother. I prefers to dress sexy even i am pregnant now. The other day, I  bought this  Dress and show it to my sister. She said It's really nice style. But she think it's too tight for me. I'm a little worry about it for sure. What do u think? What kind of clothes should I suggest for me? Thanks for any input
