We didn't know there was such a thing as an engagement dress. But when you're a celeb, there is! Nicole Richie's engagement to DJ AM never turned into anything more, but she did hold onto the dress she wore to their engagement party.
It's a vintage Halston dress worth more than $10,000. Keep in mind, Nicole was a realllllly skinny back then, so it basically fit your Barbie doll.
If you're a New Yorker, swing by Fisch For The Hip consignment store and see if you can squeeze into it!
