If you are open to secondhand clothing, Once upon a Child, especially the one in Flower Mound is awesome! They are the pickiest one I've found so far (good when you are buying the clothes). I found a brand new tags still on Easter dress for my daughter last year for $5.50. I also like to check out Ross. Babies R Us/Toys R Us just recently had a huge sale (50% of clearance prices).
The Grapevine Mills Mall is an outlet mall and they have Carters, Childrens Place, Disney, etc. I got my daughter a matching swimsuit and beach shoes at the Children's Place last year - total price together was under $7.
Maybe I'm just cheap ;) I love deals!
Good luck!
