Some of our favorite designers, models, and celeb cum designers came out last night for the Accessories Council ACE Awards. Nicole Richie — who received Influencer of the Year — looked sleek in a black Antonio Berardi gown (this designer's popularity is rapidly growing of late) while model Coco Rocha stunned in Zac Posen and a necklace from her brand spanking new Coco Rocha for Senhoa line. Petra Nemcova went for a siren-red gown from Notte by Marchesa (Marchesa designers Keren Craig and Georgina Chapman attended the event). One of the honorees of the night was accessories darling Rebecca Minkoff, who won the Breakthrough Award. She looked super chic in a black cocktail dress and one of her own clutches. The big winner? Philip Treacy, who picked up Designer of the Year. Click the slideshow to see more style highlights from last night's ACE Awards.
