Priscilla Chan’s Dress Store — No One Is Buying that Wedding Gown

Mark Zuckerberg”s freshly-minted wife, Priscilla Chan, evokes a lot of interest but not much action … according to the shop where she bought her wedding dress.

Cate Malone, the owner of the Little White Dress shop in Denver, CO, tells us the store has been buzzing with curious customers who have been trying on the $4,700 Claire Pettibone gown Priscilla wore at her surprise wedding.

In fact … traffic on the shop”s website has gone up a whopping 680% since the nuptials.

But here”s the bottom line — it”s a big fat zero, because no one has bought the dress.

Business has been bad all around this week in the world of Facebook.
