Last night at the Pierre Hotel in New York City, celebs showed their love for the new Lanvin for H&M collection!

The cocktail party and runway show drew celebs such as Sofia Coppola, Anna Sui, Emma Roberts and more, but our favorite look of the night had to be model Elettra Wiedemann's fanicful red tulle frock.

The flirty dress had a fitted bodice and full ballerina-style skirt and was accessorized with a festive necklace and a gold clutch.

The Lancôme beauty completed her look with top knot bun, minimal eye makeup, and a gorgeous pink lip for the event.

About the collection, Alber Elbaz, artistic director of Lanvin said, "[t]his has been an exceptional exercise, where two companies at opposite poles can work together because we share the same philosophy of bringing joy and beauty to men and women around the world."
