Rihanna's sparkly see-through dress at the CFDA Awards in June turned heads, and the 'Pour It Up' singer did it again as she walked the red carpet at the amfAR Inspiration Gala in Los Angeles last night (Oct. 29).

RiRi's wore a floor-length white gown with waist cut-outs, a high slit that showcased thigh-high nylons and a nearly nude bra top adorned with beaded flower accents to hide her lady parts.

At the event, the songstress presented Tom Ford with an amfAR award and honored him by wearing his design with grace and elegance.

Aside from all the schmoozing and catching up with famous friends like Justin Timberlake and Miley Cyrus, Rihanna also paticipated in the night's auction. Not only was she enthusiastic during bids, but she managed to win Harry Winston diamond link earrings. The jewelry features 72 diamonds set in platinum, which she scored for $35,000. She also dropped $100,000 on a portrait of Elizabeth Taylor at the Eden Roc by Willy Rizzo, who signed and numbered the piece.
