This style has been around for a while at Office now, but I think it would work pretty well this season, especially since it has a bit of an Art Deco vibe about it.
If you like it, and happen to be a size 3, 4 or 8 then you're in luck, because Office are selling it off at £20 (reduced from £65) along with other fun party heels like Jeez Louise (also 20 quid). If you're not any of those sizes, I'm sorry to say you might have to live without, because this is the final stock they've got. But it's rare to get so many 'leftovers' in a 4, so I thought it was worth the heads-up!
