So I found this blog of super cute maternity clothes ideas. She shows you how to rock your old clothes while only buying a few pieces of maternity wear.

She recommended these jeans from motherhood. I usually don't like motherhood things (I think they feel/look cheap.) These jeans however ROCK! So cute, and SO COZY! They almost feel like pajama jeans!
