Halloween Costume Ideas ’24: Cool Girl Edition

The Last Halloween costume ideas for 2024 are here! This time, the theme is Cool Girl. Compared to the Hot Girl edition, these costumes include more clothes. However, you can adjust every single costume to your preferences. You can take a Cool girl costume and make it shorter or take a Hot Girl costume and make it longer. Disclaimer, these Cool Girl costumes were put together based on what I find cool, clever, and even funny. 

Girl with a Pearl Earring

Johannes Vermeer’s famous painting can inspire potentially one of the most popular costumes this year. To create the look of the “Girl with a Pearl Earring,” you’ll need a white button-up shirt, a brown overshirt, a navy blue headband, and, most importantly, pearl earrings. For bottoms, wear plain blue jeans and loafers. Style your hair in a high ponytail or wrap a beige scarf around your head creating one.

Audrey Hepburn

Audrey Hepburn is the epitome of a cool yet classy girl, and dressing up as her is always a good idea. Look for a short black A-line dress and some high black gloves. Pair this with pearl earrings and a necklace, a cigarette holder, and black kitten heels. Finish the look by putting your hair up in a classic Audrey bun.

Men in black

One thing is for sure: Cool girls can definitely rock suits! For this costume, wear a white button-up shirt, a black blazer, and suit pants. Pair it with black loafers, a tie, and sunglasses. You’ll look just like a member of the Men in Black.

Running late

This costume requires a bit of imagination but is one of my favorites. Dress as a girl who’s running late, just starting her makeup, and has lost track of time. Wear your favorite pajama set and a dressing gown. Be bold and add slippers. Keep hair rollers in your hair for a playful look, and include a makeup headband. Don’t forget heavy glam makeup, otherwise, your costume might look like you’re just “going to bed.”

Party animal

This is a fun pun costume, combining a party theme with animal elements. Wear your favorite party outfit, like a black going-out top, a silver sequin skirt, and high boots. Don’t forget a party hat and animal (cat) ears — these are essential parts of the costume!
