XP from the August 2010 Mamas board:
If you're like me, you've been having some trouble finding some decent (re: not ugly) maternity clothes for a reasonable price. It's been hard because every place I seem to go either doesn't have much of a selection or is way too expensive for me (or doesn't carry anything plus size-enough for my boobs).
I found a solution.
Burlington Coat Factory.
I went there this weekend and made out like a banshee. They had a huge selection and I got 9 tops and 9 bottoms for $150. Granted, none of the tops I got were actual maternity tops because even though they had a big selection, they weren't quite big enough for my boobs. However, the tops I did buy came out of their plus size section and might as well be maternity with the way they're styled/cut. I got a few jeans (including maternity skinny jeans!), some capris, and some shorts to prepare for the warmer months ahead.
So if you're still having trouble, I highly recommend finding one near you. (Although, I have heard the selection size varies with the store so be prepared for that.)
