Looks like we have Lady Gaga to thank for inspiring celebs to dress like it’s Halloween on the red carpet. The 2012 Grammy’s were filled with some outlandish attire, but we were still able to narrow it down the 10 best dressed.

Carrie Underwood was glowing in this intricate, open-back gown.  With her swept-back blonde hair and stunning blue eyes, she outshone everyone on the red carpet.

Adele Stayed true to her classic style by rocking the retro cat eye with a gorgeous vintage style Armani gown. She arrived at the red carpet already a winner!

Hilary Scott wore this gorgeously draped gown that really flattered her figure. Her long sleek locks pulled this entire look together. Oh yeah, and her makeup? All tarte.

Julianne Hough chose this exotic black strapless gown and kept her hair and makeup simple, balancing out her entire look.

Kelly Osborne, infamous for her daring dress choices,looked chic and elegant in this one shoulder Grecian-influenced  gown. And her soft purple locks looked beautiful — Katy Perry, take notes!

Kelly Rowland knows she has an amazing figure, and in this gown so does everyone else! She chose a dress that really complimented her shape, but still looked lovely and elegant.

I usually don’t choose Paris Hilton as a best dressed candidate, but she really looked gorgeous last night. She shockingly chose a tasteful and sophisticated gown. Well done, Ms. Hilton!

Rihanna collaborated with Armani to design this  risqué little number. She definitely could have done something else with her hair, but the dress was perfect.

Jane Seymour kept it simple in this fitted, gold gown. She looks amazing, while still dressing for her age and maintaining her sexy appeal.

  Honorable Mention

Katy Perry always knows how to stand out and make a statement. Despite her blue hair her blue gown and makeup were done up to perfection.
