Kristen Stewart, Taylor Swift Show Feminine Finest At Met Costume Institute Gala

Katy Perry lights up the carpet, while Sarah Jessica Parker and Nicole Richie bring back '70s glam.

Hollywood's and New York's brightest stars lit up the red carpet at the annual Metropolitan Museum of Art Costume Institute Gala held in New York City on Monday night. In a sea of sparkling nudes and flowing black gowns, a few celebs broke the mold in bright pops of color. But as they celebrated the "American Women: Fashioning a National Identity" exhibit, most were displaying their haute couture finest.

Kristen Stewart, Taylor Swift And More At Costume Institute Gala

Kristen Stewart hit the carpet in a black Chanel taffeta gown that was very feminine for the "Twilight" star — and its sheer, beaded skirt was certainly eye-catching. Taylor Swift was all flowy romance in a long, white, vintage-inspired Ralph Lauren dress.

Nicole Richie embraced '70s disco glam in her floor-length silver Marc Jacobs gown, complete with silver sparkles and black velvet belt. Equally disco-chic was Sarah Jessica Parker in a shimmery, nude-colored pleated gown by Halston. She went a little Carrie Bradshaw with her big, matching hair-bow.

Jennifer Lopez's structured, silver Zuhair Murad Haute Couture gown had intense detailing from the bodice, down through the skirt. But Katy Perry had the most unique detailing of all: LED lights sewn into her pastel-pink dress.

Among the other stars who dazzled at the event was Jessica Biel, who kept it sophisticated in her champagne-colored Ralph Lauren Collection silk charmeuse gown (and Justin Timberlake as her best accessory). Gwen Stefani hit the carpet with hubby Gavin Rossdale in a lamé gown from her own L.A.M.B. line.

Zoe Saldana went for a one-sleeved Calvin Klein Collection navy column gown that hugged her svelte frame. Emma Watson also had a one-shouldered gown — custom-made for her by Burberry. Kate Hudson looked sexy thanks to the thigh-high slit in her blush Stella McCartney gown. Diane Kruger, there with boyfriend Joshua Jackson, kept it simple in her long-sleeved white Calvin Klein Collection gown.
