PHILADELPHIA — If diamonds are a girl’s best friend, a made-to-order $14,000 gown is going to become a blingy BFF for a few free-spending fashionistas.

An online retailer outside Philadelphia has already sold two of the gowns, which have hundreds of diamonds hand-sewn onto the bodice. They’re custom made and take about three weeks to complete.

The floor-length gown is a form-fitting strapless number with a thigh-high slit. It sells without diamonds for about $400.

Jon Liney runs the website dressgoddess.com. The diamond dress is being billed as a prom gown, but Liney says he doesn’t think the two purchases were for teenagers.
