White halter dress:  $5.99 @ Angela Fashions (RSP:  $29.99)

The material kind of reminds me of a bed sheet, but the dress is so flattering I just had to get it.

I can't believe I managed to fit into the XS.  I would have gotten a small, but all of those ones were missing some rhinestones.   I tried this size on a whim and it fit perfectly.
