Girls' Dress Help

So where do you get really cute dresses for little girls? Craig & Britta will be getting married in just a few weeks and I need to find a cute "Champagne Pink" dress for each of the girls (or cream or rust if I can't find the right pink). I've done the whole flower girl dress search on the net, but the dresses I really like are $100+. I don't want to spend that much, but I can't find cute ones that I like for cheaper. Any good sites for me to check out? Help!
