Last night was the Glamour Women Of The Year Awards, an annual event that honors inspiring and influential women for their accomplishments. This year, Glamour honored 12 women from all walks of life: advocates, entrepreneurs, pop stars, politicians and amazing superwomen who defy categorization (Malala Yousafzai).

Honored but not photographed on the red carpet were U.S. Representative Gabby Giffords and her husband astronaut Mark Kelly; actress Kerry Washington; and costume and production designer Catherine Martin.

Here are some of the attendees and honorees:

Just some ARTPOP'ers ARTPOP'ing: honoree Lady Gaga in the Thom Browne outfit that everyone knew she'd one day wear, along with a towering and petrifying pair of heels; Marina Abramovic going business-conceptual in a collared shirt.

Let's start with some good: Natalie Massenet, the founder of Net-a-Porter and an honoree, wore a baroque tailored lace dress and looked extremely chic. Lily Collins looked breathtaking in Julian McDonald. Saudi Arabian Princess Ameerah Al-Taweel radiated elegance.

A row of remarkably inspiring and powerful women, all in red: Malala Yousafzai, an honoree, who went on to very predictably and rightfully steal the show with her speech; Katie Couric; Melinda Gates, who also accepted an award.

More power womyn: Cynthia Leive, the magazine's editor in chief; novelist Jennifer Weiner; Rose Byrne in a lovely Jonathan Saunders number.

Here are some amazing women doing black right: Barbra Streisand — who won a Lifetime Achievement award — paired an Angelina-esque dress slit with a fashion bow tie because she's Barbra Streisand, goddammit. She was accompanied by her husband James Brolin. Iman looked perfect in a formal suit. Christy Turlington Burns — who was honored for her work advocating for safer maternity with her own Every Mother Counts foundation — wore black with an unconventional neck and hemline.

For a more daring take on the all-black ensemble, we have Coco Rocha in an exaggerated furry silhouette — sort of Black Swan meets the monster from Marvin the Martian in a very couture way; Karlie Kloss looking extraordinarily elegant in an embellished Oscar de la Renta dress; and Liya Kedebe — model, founder of the Liya Kedebe Foundation to support maternal health care in Ethiopia, and honoree — opting for a sheer gown with a plunging neckline.

On the blander side of black: professional surfer Carissa Moore, who received an award for her work to raise the profile of women's surfing; Hoda Kotb; America Ferrera; Hilaria Thomas.

VP of Glamour Connie Anne Phillips looked a bit casual in blue; journalist Erica Hill wonderfully combined form-fitting award show fashion with power suit vibes; Kaitlin Roig-DeBellis, a teacher who was honored for helping to save her students' lives at Sandy Hook, wore blue lace.

Ladies with a lot going on: Catharine Malandrino's sequin body suit is out of control; Lena Dunham chose a semi-sheer grid-pattern dress by Theyskens; the pattern of Gayle King's get-up is mesmerizing and unsettling.
