I don't really do maternity. I have 2 pairs of maternity jeans and two pairs of maternity slacks, and three maternity shirts. Of those items, I've only bought one pair of maternity slacks and my mom the rest because she insists I need maternity stuff. Um... no.
Instead, I just buy things a size larger (so I can wear them belted afterwards), wear form fitting stuff, wear pre-pregnancy pants with fly open, or wear regular leggings. I'm just going to wear regular cardigans and sweaters open, and layers for warmth. I may get a maternity coat/jacket if I can find one at a consignment store or on eBay. None of my coats/jackets will close over my belly and it can get really cold here at times.
