12 Favorite Looks From the Met Gala

The Metropolitan Museum of Art's spring 2015 Costume Institute exhibition, "China Through the Looking Glass," opens to the public on Thursday. Monday night celebrities and fashion insiders walked the red carpet for the annual Met Gala. There were some fabulously outrageous looks, and if you're going to be your most eccentric-self, the Met Gala is the time to show it all off. Here are my favorite looks from the night. Maybe I'll make my entrance at the Symphony Fashion Show on Tuesday in a giant cape/coat a la Rihanna.
