Last week’s Grammys were full of nail-biting tension, but for Rihanna the ceremony was a cause for celebration.

Sheathed in a darkly romantic Armani Privé custom ballroom skirt, the singer was caught taking swigs from a bedazzled flask, joking it up with Joe Jonas, and gossiping with best friend Melissa Forde.

After the event, she retreated to her Anti after party wearing hardly anything more than a sheer Marc Jacobs Spring 2017 bubblegum pink babydoll dress.

Despite not taking home any of the eight awards she was nominated for, the Bajan star, who turns 29 years old today, could not have seemed more unfazed. After all, when it comes to having a good time, the “Pour It Up” singer will not be deterred — and her personal style seems to reflect this above-it-all attitude.

The nonstop party girl, who flits from yachts in St.-Tropez to Los Angeles dive bars, always assembles a dance-floor ready ensemble that is worth celebrating. Whether toasting it up during Fashion Week in a sheer mesh top (sans bra, of course), breaking it down on the dance floor with photographer Steven Klein in a jewel-encrusted plunging-neckline gown, or ringing in the new year with a pink fur stole wrapped around her waist, Rihanna always brings a sense of abandon to her party dressing. From green fringe-embroidered Balmain jumpsuits to Dior chemise sleeping gowns, Rih ebbs from naughty to prim, from experimental to almost parochial. Heck, seeing what Rihanna will wear to a function is perhaps half the fun for her fellow revelers. Rih’s VIP booth is often where the must-have pieces of the season make their public debut: Balenciaga’s off-the-shoulder denim jean jacket, Gucci’s chinoiserie-inspired green tracksuit, or her own denim waist-holster boots.
