Here at Fashionista, we love playing buyer, stylist, beauty editor… the list goes on. If you do, too, Polyvore.com is probably proving to be an addictive guilty pleasure.

On Polyvore, you can create your own fashion layouts or look books with products or images from the web and share them with the world.

Today, the site is launching a contest with Lancôme. It’s called “Hypnotize Lancôme with Your Fashion Sense,” and it celebrates the new fragrance Hypnôse Senses. Create a layout that illustrates your sense of style, and one winner will win a $250 lancome-usa.com gift card and a bottle of Hypnôse Senses, signed by Daria. Five runners-up will each win $100 gift cards plus a bottle of Hypnôse Senses.

You can create as many sets as you like that sum up your unique fashion sense, as long as each one includes a bottle of Hypnôse Senses. After all, every fashion icon in the making needs a signature scent.

More details and entry instructions can be found here.

UPDATE: We just heard that Daria herself will be picking the winner!
