To further promote her starring role on the cover of Bryan Ferry's new "Olympia" album (see the sexy pic here), Kate Moss has signed on to guest judge a contest on the fashion-meets-tech site Polyvore.com.

Polyvore users are asked to create and submit looks inspired by Brit rocker Ferry's many Roxy Girls, the über-glam women who have graced the covers of his many albums.

The sets can feature either classic or new Roxy Girl style and will be judged by current Roxy Girl Moss, who will personally select her two favorites and announce the winners Nov. 8 (enter here).

Besides having bragging rights over the fact that Kate Moss really digs your work, the winners will walk away with a deluxe-edition album and a 40-page Moss-themed coffee table book signed by the iconic waif and Ferry.

Luckily it doesn't look like Polyvore's celebrity-studded lineup ends with Moss!

Janie Bryant, the genius costume designer behind "Mad Men," will serve as a style expert on the site next week, where she'll answer fashion questions and judge entries of "Mad Men"-inspired sets.

Three winners will receive autographed copies of Bryant's new tome, "The Fashion File: Advice, Tips, and Inspiration From the Costume Designer of 'Mad Men.'"

Ready, set, make some sets!
