Kate Middleton Dress Flying Off Store Shelves

NEW YORK (CBS/AP) Now, you can own the same white draped dress that Kate Middleton wore in her official engagement photo with Prince William. That is, if it's not sold out.

Designed by Reiss, the "Nannette" dress was purchased last year by Middleton at the company's London store. After the formal portraits by Mario Testino showed Middleton in the dress, which has three-quarter sleeves and a draped neck, it sold out in a frenzy of shopping last fall.

Reiss has decided to re-release the dress this week in the U.S. to brisk sales. The designer reportedly used a lighter fabric, but kept all the details the same.

Lyndon Mackenzie, general manager of the company's Soho store in New York, said the dress is flying off the racks and will be sold out by week's end. It reportedly retails for about $255.

While Middleton's engagement photo dress is creating a lot of buzz, Mackenzie hopes the future princess chooses Reiss for the big day.

He said he believes that dress is "going to be something very timeless and classic. Very sophisticated."

The couple will marry on April 29 at Westminster Abbey.
