I bought a very similar dress in San Francisco a few years ago. I bought it at a flea market and I haggled the guy down to $40.
Here is my version:
(It looks better on.)
Almost identical, except for the halter straps, gathered bust and the pocket. I gotta admit...I'm jealous of that pocket. Its super cute! And I wish mine were a halter as my one complaint with the dress is that the straps are a big on me.
Even though the one for $165 is a bit nicer than my version, for $40 I'm not complaining!!
