Pumpkin patch online is great, as is instore sales.
Whilst it does hit hard having to pay $79.95 for a pair of mat jeans at target etc, i found buying a few essential items - cargos, jeans, couple of tees, nice shirt ,cost me $150-$200, but that was it, i was done for the pregnancy. I also found buying 1 or 2 good quality items will see you wearing them in further pregnancies (if thats your choice ), or their great for passing onto girlfriends whom are expecting......
