Well, Mark Zuckerberg sure had a busy weekend!

On Friday, May 18th, Facebook went public—the biggest opening ever for a tech company, and the third largest IPO in US history—and then on Saturday the 19th, Zuckerberg and his (very) longtime girlfriend Priscilla Chan surprised their friends and family who thought they were coming over to the couple’s home to celebrate her graduation from medical school by announcing it was actually their wedding.

For the private ceremony, Chan wore Claire Pettibone’s Sky Between the Branches wedding gown, a laser-cut floral gown with matte sequins lined in silk, an illusion jewel neckline, a sheer back, and a chapel-length train. (Pictured above on Chan and below on the runway; how about that back?)

We think it’s beautiful and simple and easy and pretty much perfect for, you know, a secret backyard wedding. How about you?
