While the Oscars red carpet was full of showstopping gowns, we couldn't help but be obsessed with the glitzy afterparty dresses that gave the night some much-needed sex appeal. One of our favourite moments from the afterparty circuit had to be Ariana Grande's stylish return to the spotlight. After a six-month break from being photographed in public, the singer headed to Madonna's Oscars afterparty in LA with boyfriend Mac Miller. The songstress ruffled some feathers in a plumage-adorned, off-the-shoulder Saint Laurent dress that retails for a whopping $11,900. Her signature over-the-knee boots, simple jewels, and slicked-back platinum blond hair completed her sexy date-night look. Read on to see Ariana's afterparty ensemble and shop her exact designer dress, as well as similar feathered frocks at a much more affordable price.
