I got fishermans pants, a strapless black dress and a couple of tops from Maternity-Me online for $25 a piece. They always have sale items for $15 - $25.

I got my jeans and another top from Pumpkin Patch on sale. Black pants for work I got from a local maternity shop. They were $90 and I wore them every day until I started mat leave

Also got a few cheapo $10 normal baby doll style tops from Cotton On and still able to wear them now, good for hiding post baby belly
