It was a big night and all the stars wanted to look their best. The Metropolitan Museum of Art Costume Institute Benefit, an event meant to highlight the institute's latest fashion exhibition - Schiaparelli and Prada: Impossible Conversations - invited the most glamorous of Hollywood and the fashion industry and everyone showed up dressed for the occasion.

The celebrities at the event wore a mix of gorgeous gowns, glittering dresses... some were glamorous and some, unfortunately were not.

For example, new mother and global pop star Beyonce Knowles wasn't quite her usual stunning self - the sequined and feathered Givenchy Haute Couture gown with the skin tone bodysuit underneath - was a poor choice. Meanwhile, singer Florence Welch, of the band Florence + Machine, wore an Alexander McQueen outfit with outsized sleeves, while actress Christina Ricci's pink and black Thakoon dress with a gigantic bow was a fashion disaster.

In addition, while supermodel Anja Rubik seemed to look beautiful but then spoilt it all with an unnecessarily high slit for her dress. Model Coco Rocha was not far behind, with a vintage Givenchy in pink and yellow - it did nothing for her.

Kristen Stewart, the star of the Twilight series of films opted for a strapless snakeskin leather type and color-block Balenciaga dress, teamed with white booties and The Descendants actor Shailene Woodley choose Christopher Kane's slick floral-infused column dresses, which could have been better.

Elizabeth Banks sported a mixed-media print dress by Mary Katrantzou, with a high neckline, peplum bodice and a thigh-high slit and wore a pair of embellished crystal-heel Christian Louboutins - once again - it didn't quite work for her. Actresses Kirsten Dunst and Eva Mendes came in orange frocks and would have better stayed at home. Fellow actress Chloe Sevigny came in Miu Miu's black mirrored geometric patchwork mini dress and shoes and a clutch also by Miu Miu and Repossi jewels - too shiny?
