The Grammy red carpet is usually an outrageous display of over-the-top ensembles, and while some stars did show up in fashion-forward looks, others opted for more traditional awards show attire.
Never one to play it safe, Rihanna stepped out in the night's sexiest look; a black plunging Giorgio Armani dress with an extremely low-cut back and racy thigh-high slit.

Instead of her usual wacky get-ups, Katy Perry shocked her fans with a feminine pale blue embellished Elie Saab design, which featured three-quarter sleeves, a scoop back and ribbon belt. Even her bright blue hair was swept back in a glam updo.
Taylor Swift stuck to her signature nude, sparkly look, in a stunning gold cap-sleeve Zuhair Murad Couture gown, which featured a high neckline and train. She accessorized with Neil Lane jewels and wore her hair in a sophisticated ballerina bun.

Fergie went for a traffic cone-orange sheer lace Jean Paul Gaultier Couture creation (which was shown on the designer's Paris runway just two weeks ago) with visible black bra and panties underneath and Neil Lane jewels.
Some of the night's craziest looks included Nicki Minaj's nun-inspired red Versace, Robyn's all-white outfit and Sasha Gradiva’s bizarre gun accessories.
