Beyonce curvy in Givenchy New York - Arabstoday Beyonce Knowles was a contender for worst dressed at the \"Met Costume Institute Gala\" in New York. The usually stylish singer donned a Givenchy Haute Couture gown for the occasion, but the sequined dress with feathered train failed to impress, although it showed how the star gotten back into shape since giving birth to daughter Blue Ivy in January. However, she kept her accessories and makeup to a minimum and pulled her hair back into a simple, sleek ponytail. We think that the singer’s bum baring dress couldn\'t compete with the other elegant and classy gowns.
