After his company went public, Mark Zuckerberg married his longtime girlfriend Priscilla Chan. Sneaky! And savvy, say the lawyers.

Zuckerberg posted the pic at left on his Facebook page on Saturday — 1.2 million-plus likes! — and today, the designer behind Mrs. Zuckerberg’s dress, Claire Pettibone, is feeling the love too. People are beating a path to her homepage, wanting to get one of the $4,700 dresses Chan was married in. The designer’s website got an added 24,000 visitors because of the dress.

The dress is available at Kleinfeld’s in New York and the store’s PR team says it’s still available.

Here’s some info, in case you want to learn more about Cilla.
