When your wardrobe is full of museum-worthy looks, there's really only one place to party...

This past Tuesday night, New York's style staples stepped out in their most glittering ensembles. 

The occasion? 

Cult favorite online boutique Couper's fabulous fête at The Inaugural Hall des Lumières.

Sequins and paillettes aplenty filled the downtown art destination for cocktails, a divine display of bites curated by Romilly Newman, and a special viewing of the venue's latest exhibition, Gustav Klimt: Gold in Motion.

Curious to see who wore what to the exclusive soirée?
