Fashion Rihanna Reminds Us Gowns Aren't the Only Hollywood Look Welcome to "Who Won Fashion Today," where we award the boldest, best dressed person of the day.

Rather, we reward risk-takers—those that stay true to their personal style and make us go, "Now THAT is a LEWK.” By Ruthie Friedlander Ruthie Friedlander Twitter Ruthie Friedlander is a New York-based writer, editor, and founder of the At Large Agency.

But let’s be honest. We’ve seen a lot of gowns since Sunday. And while I’ll never tire of a pretty dress, looking at all these gorgeous women in heels and fancy dresses makes me yearn for a casual, cozy outfit. Rihanna Goes Girly with Her Newest Fenty x Puma Collection Today, I really considered wearing sweatpants. But then I remembered I’m not Rihanna. Last night, Rih was hanging at Tao in New York City wearing a super cozy fleece lace-up jumpsuit from her eponymous Fenty x Puma Collection. And while she was wearing sky-high booties, that jumpsuit looked like the chicest snuggie we’ve ever seen. 3 Outfits to Wear with Rihanna's Fenty x Puma Trainer Courtesy Image zoom With a Slip Dress and Tee The slip dress is one of this season's hottest pieces—give it a dose of cool-girl appeal with a tee layered underneath, a statement-making purse, and a geometric cuff.
