I bought a lace dress like this from Forever 21 a few weeks ago. I could not find any pictures online, but could take one of mine when I get home if you would like! I actually found out about the dress when I was reading "Where Did You Get That Blogspot". She is super adorable, and a PF member too! She has a few pictures of herself wearing the dress! HTH
I think I found your dress....my friend owns a store here in dallas, and she has a dress that is extremely similar. If you would like...pm me and I will give you her contact info and she can email you a pic.
