You mentioned Target but have you checked Target online? I just got a bunch of cute stuff. Their online selection is often quite different than the brick and mortar stores
I've ordered maternity clothes from ASOS, H&M, Loft, Target, Old Navy, and Walmart.com.
Believe it or not, most of my work blouses are from Walmart.com and the ones I get most compliments on. I just wore one the other day and got lots of compliments. I can't think of the exact brand, but I have seen the brand sold on Zulilly as well.
I just ordered a ton from a pea in the pod. Full price items are 30% off, clearance everything is buy 2 get 1 free, and there is free shipping. All ends today I believe!
