Each of these Givenchy masks took 12 hours to apply at Paris Fashion Week, but we're not suggesting you put in those kind of man-hours for your Halloween get-up. Instead use stick-on body crystals, like Swarovski Crystal Tattoos (remember when you used to rock those crystal butterflies in the '90s?), and apply generously around your eyes. Voila! You're a new superhero -- Glam Girl. And your arch nemesis is anything drab.

The makeup at Vivienne Westwood was either jaw-droppingly stunning, or similar to what it looks like when I try to apply my makeup during rush hour. Either way, I was so transfixed by it, I had to come up with a Halloween costume to fit the look. Create an updated Black Swan look with that old tutu you can't seem to part with, or go for a sinister Cruella Deville.

This colorful look from The Blonds New York Fashion Week show is completely versatile. Whether you're going as a mermaid, a fairy, or the designers' inspiration -- Tweety Bird -- we'll help you recreate the look with this step-by-step tutorial.

Leave it to Betsey Johnson to come up with a totally crazy, out-of-the-box look ... that we're actually dying to wear in real life. Whether you take on every aspect of the look, or just one statement-making feature -- you can let your imagination run wild with possibilities for this look. The crazy pink hair and rosy cheeks make for a modern china doll. That silver lip? Perfect for a futuristic fem-bot. Our beauty picks: Obsessive Compulsive Cosmetics Metallic Lip Tar and Bumble and Bumble and Bumble Spray Chalk.

The models at Thom Browne were split into groups of nurses or patients (we're not sure which category this woman falls in), but her look screams The Joker to us. Smear and smudge to your way to this Halloween look. The crazy eyes are all on you. For a matte red lipstick we love NARS lipstick in Jungle Red. Apply it to your lips then use your fingers to smear it around your mouth. Set with a translucent powder to avoid smudging the whole lip color off.
