The biggest question in the fashion industry — who made Chelsea Clinton’s wedding dress? The bride-to-be was spotted entering Vera Wang’s New York studio, wearing a big floppy hat, reportedly for a fitting. The mother-of-the-bride, Secretary of State Hillary Clinton, is also getting ready for the big day. Hillary Clinton is rumored to be wearing Oscar de la Renta.

UPDATE: Indeed, the wedding dress was designed by Vera Wang. Get more info and see the pictures on our updated post: Chelsea Clinton Wedding Dress Designed By Vera Wang

The cost of the wedding is estimated to include $125,000 to $200,000 for the venue, $750,000 for the catering (by Blue Ribbon Restaurants, St. Regis and Olivier Cheng Catering and Events), $250,000 for the flowers, $40,000 for the music, $35,000 for photography, $30,000 for security, and $15,000 for the wedding dress.

WWD’s Wednesday, July 28, cover features Chelsea Clinton, obscured by a large floppy hat, arriving at Vera Wang’s midtown showroom in New York City on July 27 to meet her Secretary of State mom, Hillary Rodham Clinton, who was already there. Reportedly, Wang is doing the bridesmaids’ dresses, the flower girls’ dresses, as well as the all-important wedding dress. And supposedly Hillary and Chelsea have met with Wang five to 10 times over the last four months

Rhinebeck has been buzzing for weeks in anticipation of the high-profile nuptials between the former first daughter Chelsea Clinton and her longtime boyfriend, 32-year-old Marc Mezvinski, an investment banker. Extensive preparations have been made, and reports speculate that the wedding costs could total $2 million.
