What a stylishly bittersweet moment!
One day they'll be talking about this historic event with their future children and grandchildren!
The sisters both wore Louis Vuitton for the occasion, with Elle selecting an embroidered white skirt suit from the Resort 2014 collection, while Dakota vamped it up in a black lace maxi dress with sheer bottom half.
Both also opted for teal sandals, but Dakota brought an element of surprise with her uncharacteristic, wispy updo. We love it when she wears her hair up!
Don't they look so chic?!
