Met Gala 2014: Best And Worst Dressed On The Red Carpet; Power Couples At The Metropolitan Museum Of Art’s Costume Institute Benefit Ball [PHOTOS]

The Met Gala 2014, the annual ball that kicks off the Metropolitan Museum of Art's yearly Costume Institute exhibit, is always a dazzling fashion parade.

This year's event -- held Monday evening in New York City with a theme in tribute to Charles James, the British fashion designer known as "America's First Couturier" -- had its share of best- and worst-dressed celebrities.

WORST DRESSED

Those on the worst-dressed list included Lena Dunham, who wore an unflattering strapless dress, while Kate Upton’s black sheer getup didn’t go down well. Lupita Nyong’o wore a feathered Prada dress with emerald jewels and a headband, which also turned out to be a disappointment from the usually exquisite young star. Others who made the "worst" list were Shailene Woodley, Elizabeth Olsen, Solange Knowles, Katie Holmes, Maggie Gyllenhaal, Kirsten Dunst and Lea Michele.

BEST DRESSED

Stars who dazzled on the best-dressed list included Reese Witherspoon and Kate Bosworth, both in rosey-hued Stella McCartney gown. Blake Lively's dazzled in a Gucci dress, while Diane Kruger's silver gown by Jason Wu for Hugo Boss caught all eyes.

Other celebrities who did not mess up on their style included Suki Waterhouse, Zoe Saldana, Emmy Rossum and Kendall Jenner.

Check out the list of couples, who sparked the red carpet with their brilliant chemistry and style.
