London: Katy Perry lit up the Costume Institute Gala Benefit at The Metropolitan Museum of Art, when she arrived for the A-list event in a dress with glow lights fitted on to it.
At first glance, the `I Kissed A Girl` hit-maker`s gown looked relatively demure for the famously kooky dresser.
Floor-length, pale pink and white, it seemed she had decided to play it safe.
But then the lights went down, the 25-year-old began to glow in her fantastic colour-changing dress. Concealed rows of fairy lights gave the CuteCircuit design a fluorescent aura at the star-studded event, which attracts the toast of New York society, reported Daily Mail online.
As she walked down the red carpet all eyes were on the glowing singer, who accessorised with Christian Louboutin shoes and Lorraine Schwartz jewels.
She was attending the Costume Institute Gala Benefit to celebrate the opening of the `American Woman: Fashioning a National Identity` exhibition at The Metropolitan Museum of Art.
"I feel like I really have to represent those girls that just go for it and do their own thing and, you know, have their own bit of spontaneity and self confidence," she said.
"I think sometimes in fashion it can get a little stuffy so I wanted to lighten up!" she added.
The gala was attended by some of the biggest names in the world of film and fashion including Sarah Jessica Parker, Stella McCartney, Kate Hudson and Gisele Bundchen among others.
Perry left fiance Russell Brand at home for the evening, instead arriving on the arm of a designer friend.
TV talk show host Oprah Winfrey and Vogue editor-in-chief Anna Wintour co-chaired the annual bash, along with Gap creative director Patrick Robinson.
