Hello maternity clothes, goodbye sense of style

I caved and bought maternity pants last night. My normal pants won't button anymore and the Bella band works ok but I still feel like my pants might fall off at any minute. Especially when I'm speedwalking around the arena on game days. I have to say that I'm very disappointed in the maternity clothes at Target and Kohls; I was hoping to avoid spending a fortune at the maternity stores in the mall but I may have no choice. So I've got one pair of work pants and I figure I can get away with wearing then twice a week and rotating in leggings and maxi dresses. I winder if I could get away with yoga pants?
