2010 Halloween

There are few movies that made a bigger impact than Avatar, and there are probably few things cooler than a leggy, blue Avatar chick for your own Fabby Halloween. Now, don't panic; getting a Na'vi's look is easier than it looks. Just think of a serene blue palette and feathered jewels. Try abstract printed swim separates ($18, originally $39), then add shredded leggings ($38), and pile on the eclectic jewels — and don't forget your blue face paint!

Military-chic is a huge Fall trend, but with just a few tweaks and additions, it can easily turn into your next Halloween costume. Ready for battle? Throw on an army green shirt ($220) — preferably with patches on it, lace-up boots ($120), a military hat, a dog tag necklace, and anything else military-inspired you can find. The key is to pile it all on — you don't want to look like you would on a normal stylish day. Click on the items above to get the hot military babe look.

We have Mad Men to thank for its ladylike influence on Fall trends, but if you care to take it to the next level, channel the '60s-era femme for a Fabby Halloween. Think full skirts on dresses ($60, originally $109), satin fabrics, pencil skirts, and a tie front blouse for a perfect, retro-sultry vibe. Then, finish with luxe little details: bows on pumps, crystal jewels, and oversized stud earrings ($14). Click the items above to get started!

Black Swan, starring Natalie Portman, doesn't come out until December, but that doesn't mean we can't embody the brooding, beautiful ballerina for Halloween. While we won't be able to score the Rodarte-designed wardrobe, we can re-create it via a black tutu ($352) and black ballet shoes ($20). Consider getting your Black Swan makeup done by a professional, and don't forget to watch the trailer to help you get in character.

It's time to start brainstorming for your very own Fabby Halloween! This year, we're kicking it off with Katy Perry's sequin-injected California Gurls look. To get the candy-girl's whimsical look, start with a pink bustier top and high waist denim shorts ($20, originally $44), then add your own Fab embellishments with glittery sequins and candy — rainbow lollipops are key. Finish the look with a pair of stripe knee-high socks ($24 for three, originally $30) and sneakers, or a pair of red or white heels to up your flirty factor. The more candy-color and glitter, the better! Get inspired and click the items above to shop the look.
