PepsiCo has tapped British designer Richard Nicoll to create a dress inspired by the newest edition of its Tropicana juice line, Trop50.

At 100 percent silk, the sunny, orange and coral one-size-fits-all dress was created to promote the new low-calorie orange juice.

Sweetened with a natural plant extract, stevia, the new juice has 50 percent less sugar and 50 percent fewer calories than regular juice.

Only 50 of the dresses, adapted from Mr. Nicoll’s trademark Stella t-shirt dress, have been created and are available exclusively on Atelier-To-Go for £555, or nearly $900.

Features include a keyhole button fastening at the back of the neck, short sleeves with double buttoned cuffs and a contrasting orange block of color at the back.

Sales profits will go towards Fashion Targets Breast Cancer ; the leading charity fashion campaign by Breakthrough Breast Cancer.

The move is Tropicana’s first designer collaboration, and comes in the same week that Diet Coke announced designer Marc Jacobs as its creative director for 2013.
