One of the biggest nights in fashion will happen on Monday when The Met's Costume Institute fetes its newest exhibit, "American Woman: Fashion a National Identity."

Keeping with the Americana theme, Oprah Winfrey, Anna Wintour and Patrick Robinson of The Gap are co-chairing the gala. Yet, while fashion companies who sponsor the ceremony usually dress a good amount of the attending guests, The Gap, obviously, isn't exactly a ball gown maker.

Alas, the company, which was founded in San Francisco in 1969, has solved that problem by recruiting a cast of CFDA/Vogue Fund-winning American designers, including Alexander Wang, Kate and Laura Mulleavy of Rodarte, Thakoon Panichgul and Michelle Obama fave Sophie Theallet, to collaborate on Gap evening wear for the event.

Wang x Gap gowns will be worn by M.I.A. and Zoe Kravitz, Rodarte's dresses will be donned by the Mulleavy's muse Kirsten Dunst and model Jamie Bochert, Kerry Washington and rock and roll heiress Riley Keough will choose Thakoon for Gap and Jessica Alba and Vera Farmiga will sport Theallet's Gap designs. Besides Theallet, all of the designers have worked with The Gap on past collaborations.

The day following the May 3rd event, the eight Gap designs will be auctioned off at until May 31st, with proceeds benefiting the Costume Institute.

And for New York-based fashion fans wanting to see the gowns up close, they can check them out in person at The Gap's Fifth Avenue pop-up shop, where they will be showcased alongside seven styles of Gap t-shirts, $34.50-$44.50, celebrating the American Woman exhibit.
