Rihanna was a showstopper on the red carpet at Chanel's haute couture show in Paris on Tuesday. She wore a long, slouchy cream-colored cardigan, unbuttoned down to there and up to here -- in fact, only three buttons right around the middle seemed to hold it together. She accessorized with ropes of pearls and a floral brooch. What she didn't wear was a bra, and it was possible to see a nipple ornament under the thin sweater fabric. [The Cut]

He tells writer Mark Holgate, who spent two days with him in April, that he almost turned down the job because he was preoccupied with his own brand, and also feared being the "most hated man in fashion" if he replaced the departing Nicolas Ghesquiere. But he consulted a psychic, who told him it was his destiny. [Vogue]
