In what they hope will be an upgrade from fashion scrapbooking sites like Polyvore, the founders of Like.com have created Couturious.com, a site that allows users to choose items and put them together on an avatar, creating a “virtual styling experience.”

Basically, you’ll be able to go online and mix and match pieces on a mannequin until you find the outfit you want, like Cher could in Clueless. Then, of course, you’ll be able to buy that outfit.

The site has teamed up with New York-based fashion labels–Alice + Olivia, Cynthia Rowley, Charlotte Ronson, Tibi, Tory Burch and Yigal Azrouël–who have provided images from their Spring 2010 collections. More collections will be added as Couturious grows.

This is the forth fashion-related site started by the San Mateo, Calif.-based Like.com. (The others are Covet.com and Weardrobe.com, and each has an e-commerce component.)

While the company won’t reveal annual revenue, it did say that e-commerce sales made through the Like.com family of Web sites reached $100 million in 2009. (Like.com gets a cut of those sales but the actual transactions are made on other sites.) The company has raised $30 million in financing from venture capital firms like Menlo Ventures and Leapfrog Ventures.

Will you use Couturious over Polyvore? Here’s a video preview of the site:
