Grammys 2012: Best & Worst Dressed

While Fashion Week soldiered on in NYC, music's biggest stars flexed their style muscles and brought some panache and designer labels to the Grammy Awards in Los Angeles on Feb. 12. But, you can't win them all, so from Nicki Minaj's nun look to Rihanna's not so innocent gown, here are our picks for the 10 Best and Worst dressed of the evening.

BEST: Taylor Swift | Taylor continues to rock her signature golden goddess look, but this time added some modern edge in this elaborate Zuhair Murad gown. The country princess accessorized the look with Prada shoes, and Lorraine Schwartz jewels.

WORST: Nicki Minaj | The rapper sought fashion inspiration in Mother Teresa for the Grammys. Minaj made her way down the carpet in a red nun-like Versace ensemble. While not very figure-flattering, the rapper has our vote for most creative outfit of the night. She also had the hottest accessory of the evening, the Pope on her arm.

BEST: Adele | Grammy queen Adele looked like a classic Hollywood starlet in a custom black Giorgio Armani gown drenched in black sequins. The Vogue cover girl crowed her look with a 12.4 carat Harry Winston diamond ring.

WORST: Rick Ross | The rapper defied the protocol of the red carpet in this too-casual sweater look. Perhaps he just rolled out of bed and grabbed the first world's most outrageous sweater he could find?

BEST: Rihanna | Someone looked badass chic in a black silk custom Giorgio Armani gown with a jaw dropping plunging neckline. The multi-nominated singer ever so delicately accentuated her lady parts with an enticing Jacquie Aiche necklace and diamond and gold snake armlet. Winning for best dressed of the night, Rih Rih punctuated the salutary gangster look with Christian Louboutin shoes.

WORST: Robyn | The Swedish singer couldn't decide if she wanted to wear a mini or long dress, so she chose both, resulting in a severe look. She continued to shock, in all the wrong ways, with a pair of khaki platform shoes.

BEST: Katy Perry | The "Firework" singer cascaded down the red carpet in this stunning pale green princess-inspired Elie Saab creation, $2 million worth of jewels from Norman Silverman and Christian Louboutin heels.

WORST: Sasha | The Russia-born dance pop star channeled the terminator in this valiant but ultimately bizarre look. She transformed her arm into an arsenal adding some aggression to her delicate pink look. Who ever said guns go with everything was clearly mistaken.

BEST: Sophia Grace & Rosie Brownlee | Sophia Grace Brownlee and her hype girl Rosie added some sweet and cheeky flavor to walk the red carpet at the Grammys. The two darling ladies -- famed for their raps aired on "Ellen" -- looked pretty in pink in their signature tutus with some added golden flare.

WORST: Lady Gaga | The 'Marry the Night' singer appeared to be doing just that in this black veiled custom Versace ensemble. Mother Monster was a bit more toned down then we would have liked to see her, but still managed to grab attention rapping her entire body and face in fishnet. We love Gaga's dark temptress look, but honestly expected something a bit more grand and glitzy.
