Tech royalty just does not inspire the same copycat behavior as the real thing. Priscilla Chan stepped out at her surprise wedding in a $4,700 Claire Pettibone dress, but TMZ reports that the white creation isn’t exactly flying off the rack at the Denver store where Chan bought it. Chan wed Facebook founder Mark Zuckerberg in an unannounced ceremony shortly after the company went public. Cate Malone, the owner of the Little White Dress shop in Denver, told TMZ that many inquisitive brides-to-be have been trying on the gown, and that traffic on the shop’s site has been up 60 percent since the wedding—but in a twist Chan’s new husband can likely relate to, sales are not living up to the hype: no one has bought the dress.
