Blue hair doesn't blend in, but lucky for you metallic are in. Sure you can go the low key route with chrome nails, but why do that when you can buy this starry skirt that is actually office appropriate? Tuck in a collared shirt and you'll be the trendiest babe in the office, guaranteed.

A cowgirl is a perfectly legit costume, but you don't need a poufy dress to get the point across. For a fashion girl take on farmer chic, a pair of overalls will not only upgrade your costume, but also your wardrobe. Just think of all the winter sweaters and button-ups you'll be able to layer under them this season.

Somehow skeleton costumes always translate to sexy, but with this rad sweatsuit you can change that notion. For your more casual Halloween parties, this set will look cute and comfy. But mostly, it's worth the investment because you know you'll be wearing it day in and day out for the rest of winter.

Half the fun of dressing up like a devil is wearing something a little naughty, but devil horns are kind of hard to get away with at brunch. To get mileage out of your getup, a feisty one-piece swimsuit that doubles as a bodysuit is the man for the job. You'll have it at the ready for impromptu hot tub sessions, not to mention nights on the town when paired with leather leggings and boots.

Getting frisky on Halloween is a hoot, but what's not is spending a fortune on a dress that you'll never wear again. If you decide on Jessica Rabbit, shop with a purpose for a semi-formal red gown that can swing both classy and sultry. You'll no doubt be rewearing this bad boy for dressed up occasions of all kinds.

Chances are that at some point in Halloween past, you portrayed a princess. If you were under the age of 15, that likely include a very fluffy tutu and an aggressive amount of glitter. For a more grown up take on royal, a subdued pink dress in a velvet fabric just feels right.

A touch of animal print never hurt anyone, but even on Halloween, a skintight number is going to get you noticed. That's not a bad thing, but if why go the second skin route when you can opt for a stylish burnt orange romper that will be equally as exciting when paired with booties and a leather jacket.

Again, not super practical. Instead? Get the point across with a vibrant magenta powersuit. It's a bit of a splurge, but think of it as an investment piece. Not only will you be the cat's meow on Halloween night, but you'll also be the most polished one in room at that Monday morning meeting.
