I love the Bella band.   I had one in black and one in white and used them both during two pregnancies.

My favorite part was getting a couple of extra months in my favorite non-maternity pants and jeans so that I wasn't so sick of my maternity stuff by the end. 

I was skeptical that a little cloth band would actually hold my pants up, but it really worked.  It also helped with briding the gap between the end of my shirt and the top of my pants so that no skin was showing - so it made the non-maternity shirts work for a few extra weeks too!  The lok was as though I was layering two T-shirts....
