Rihanna's Week of Fierce Fashion

The singer shows her charitable side in head-to-toe Louis Vuitton – including lace-up boots, a bubble skirt and a puff-sleeved silver top – along with stacked Noir spike rings at the DKMS 3rd Annual Linked Against Leukemia Gala.

Having already appeared as the face of Gucci for their UNICEF collaboration, she turns into the house’s best model in platform sandals, cropped khakis and a snake-print top – all from the Italian label.

Paging John Travolta! Rihanna puts a distinctly feminine and ultra-cool spin on her Derek Lam white suit with a plunging leopard-print blouse, bold red lips and a long Yvel pearl necklace.

What to wear for a shopping excursion downtown? For Rihanna, the answer is towering heels, J Brand “Zombie” jeans and a corset.

The singer channels Michael Jackson in her sharp-shouldered yellow jacket with sparkling lapels and skinny black jeans for a night out on the town.

Rihanna got the fashion blogs buzzing by pairing a zip-up poncho and denim cut-offs with $920 Rodarte leather thigh-highs and Acne peep-toe booties.

While others may have gone for over-the-top gowns, Rihanna stuck to her own path in a mega-shouldered Dolce & Gabbana suit for the Metropolitan Museum of Art’s Costume Institute Gala.
