I just ordered a t-shirt from CryBaby Maternity, and their shirts and customer service are WONDERFUL. I wore lots of "potato sack" maternity outfits, and sweatpants/big t-shirts with my first child, had a little bit better options the second time around...but now 5 years later from the time I was pregnant the last time-the choices are MUCH better.
I actually am looking around and finding stylish maternity and nursing clothes that look like stuff I would normally wear.
(Although, luckily with hard work and my few years here at 3FC, I ordered the tee from CryBaby in a regular size L, not plus sized.
P.S.-Since this is my third child, I purchased the "Fertile Goddess" tee from CryBaby.
