In the new cover story in Vogue, RiRi says, "There’s people with way more talent than I when it comes to singing. Bigger voices. But people want to know who you are. Fashion is a clear indication, a way to express your attitude, your mood.” 

Speaking of fashion, RiRi has a simple explanation for why bras aren't always part of her look. “If I’m wearing a top, I don’t wear a bra. If I’m wearing a bra, I just wear a bra.”
