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!

Fact: Bloggers have been endorsing Polyvore like celebs endorse presidential candidates. But it took us a little while to jump on the bandwagon (blogwagon?) with this one. But thanks to Polyvore, now you, too, can play Rachel Zoe from the comfort of your own laptop.

If you’re new to the game/just bored like us, you should give it a try. Then spend all day not working, and instead mixing and matching your Net-a-Porter pipe dreams or taking your own wardrobe and pretending you have Cher Horowitz’s closet (so ahead of its time). Even the offical Polyvore Blog is addictive.

And retailers, take note: Polyvore is also a pretty genius marketing tool. Hot stops like Nine West have been holding contests and giving away merch to the users who create the best looks using their products.

Now let’s commence plotting on how to get Net-a-Porter to jump on board and give us free stuff…
