While Mary-Kate and Ashley Olsen are notoriously press shy, the designing duo behind The Row are finally opening up in an intimate behind-the-scenes look at the planning of their Spring 2011 collection, which shows in Paris on Oct. 3.

Bing.com is filming the ladies right up to the moment of the event and premiering its exclusive footage on bing.com/therow on Oct. 4 at 7:30 p.m. ET.

The three-minute video will show the twins working in their New York atelier -- snipping hems, adjusting necklines, casting models -- and reveal their Spring 2011 sketches.

It will also show clips from their Parisian runway presentation and an interview in which the former "Full House" stars discuss their line and its inspiration.

"We named The Row after Savile Row," Ashley explains in Bing's sneak peek. "The first piece that we really explored was a T-shirt and from then we've just expanded on all different categories, with always the mentality of refined minimal luxury that was wearable."
