A.S.
Believe it or not, I picked up a few simple, cute cotton dresses from Wal-Mart for about $10. Not maternity, just a size up from my pre-pregnancy size. Add some simple jewelry and cute, comfy sandles, I and feel dressed up! FYI - I'm 31 weeks along, I bought my dresses last month, and I plan on wearing them in the hospital after having the baby, instead of walking around the maternity ward in those lovely hospital gowns.
ETA: here is the link so you have an idea of the style I'm talking about.
