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.

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.
