In love with this gold on black on black look from Cheyenne Meets Chanel. So sleek, and I'm really digging the gold statement belt. It's like: KABOOM. You could put that on with anything. The Maje belt below is a close version to the one in the picture, along with some other alternatives.
**Updated 3.13.13: See below for DVF option!**
Maje Metal Panel belt
I'm also considering the Rachel Pally Ida dress, in large part because the dress comes with the BELT!
This version from DVF is a nice, relatively affordable alternative to get the look.
