From left, Ellie Goulding won the night in a Stella McCartney blush-pink slip dress with beautiful back detailing. Despite the Grammys' crazy fashion reputation, Goulding's approach was elegant and pretty. We love that she stood out by playing it simple. Her high, tousled part and diamond collar necklace kept the look sexy and glamorous.

Kacey Musgraves stunned in a super-textured ombre Armani Privé gown. Nominated for best country album, Musgraves rocked a trendy matte purple-toned lip, and we love that her confident, quirky personality was so evident in her look.

John Legend donned a playful dotted suit jacket, a departure from his usual straightforward approach. Plus, how cute was the clean-cut singer next to his beautiful pregnant wife Chrissy Teigen?

Taylor Swift got mixed reviews on Twitter for her mega-hot Atelier Versace bandeau crop top and bright-pink, high-slit skirt, but we love how youthful, playful and sexy this look is. Plus, her new Anna Wintour bob is beyond fabulous. Our only critique? The jewel tone color scheme was a bit reminiscent of last year's teal blue — change it up, Taylor!

Demi Lovato kept her always-edgy vibe in a Norisol Ferrari blazer and maxi skirt. The look featured a plunging neckline, high slit, black pumps and plenty of silver statement jewelry. Sexy and chic.
