Two outfits weren't enough for Rihanna at the Oscars. After stepping out in a sheer black and leather Alaïa dress on the red carpet and wearing an embellished black Maison Margiela bra with print pants on stage during her performance, Rihanna switched into a third show-stopping number: a lime green bustier and skirt from Bottega Veneta with a shearling stole set and gloves. Fans shared a look of the ensemble in the audience, as Rihanna joined her boyfriend A$AP Rocky to watch the rest of the show after her performance.

Rihanna had stuck to black earlier in the night. Now that the Oscars have wrapped, there's a good chance she could debut a fourth outfit if she chooses to go to an after-party.

Here was her red carpet look:

And her performance look:

Rocky, of course, was in a white suit next to her during the ceremony. He received some fan attention for his enthusiastic standing ovation for Rihanna after her performance.

Rihanna is expecting the couple's second child. In a recent interview with British Vogue, she spoke glowingly about Rocky's relationship with their firstborn, their son whose name they haven't shared publicly yet. “I’m just sitting on the sidelines when they’re together. I’m literally the girl trying to get into the boys club, waiting for my turn,” she said. “He is obsessed with his father. And I’m like: ‘Didn’t I give birth to you? What is going on?’ Their connection is undeniable. The second Rocky makes eye contact with him he is on fire. The whole thing they say about sons and moms, it’s a myth. Sons and fathers is crazy. I realized that the validation that you really need as a boy is from your father.”
