Halloween Costumes Made from Things You'll Actually Want to Wear Again

Although the trench coat never went out of style, it's definitely having a major moment this fall. If it's not already on your shopping list, it definitely should be. Take this piece and wear it more as a dress -- add a pair of leather riding boots and a magnifying glass and instantly a costume mystery is solved.

You can never own enough basic turtlenecks, and this striped style is the perfect fall layering piece. Pair the top with skinny jeans from your closet (or the pair we listed below) and add a painting brush (plus, a black beret if you really want to get fancy) and you're set!

Lingerie-inspired pieces are still a huge trend this fall -- particularly the slip dress. Layering this slinky piece over a turtleneck is one styling trick you'll want to try. Plus red is one of the hottest hues of the season. And while the length is a little longer than the one Cameron Diaz wears on the famous VHS cover, the dress definitely still gives off Mary vibes.

A navy blazer is a wardrobe staple, so if you don't have one, it's worth the investment. Pair it with the matching pencil skirt (which goes with everything) for a very stylish flight attendant uniform.

Denim overalls have become almost as much of a staple as skinny jeans. Rock a pair with a plaid button-down shirt ( another great fall go-to) and pick a shovel or broom at your local hardware store -- tractor optional.

This shoulder baring silhouette isn't going anywhere, so no guilt with this purchase because you'll be wearing it all next spring and summer. Pair it with a black trouser for a very chic Waldo vibe. The classic pant feels very of-the-moment with the cinching high waist. Add a striped beanie for the total "Waldo" look.

There's nothing more classic than an LBD. Pair this chic sleeveless dress with black gloves and a rhinestone hair comb and you're instantly Audrey Hepburn! (The Big Little Lies cast will be very proud.)
