There are a lot of versions of the Cupid costume online, but this one was by far one of my favorites.

I love how she chose to go for an all-red look and add the accessories to make it a hot Halloween costume like the fishnet tights or the wings.

This gypsy costume is super cute and easy to recreate. My tip is to add as much jewelry as you can and combine it with a fringey skirt.

Getting a pack of fake tattoos will be the cherry on top to complete the whole look!

11. Carrie

She’s one of my top 10 hot Halloween costumes for girls.

Jennifer from Jennifer’s body is an icon. Not only she’s smart and terrifying, but she’s also one of the hottest horror movie characters of all time.

And since the movie turned 15 years old this year, I guess this is a good time to be her for Halloween!

14. Barbie Costume

The Barbie costume is such a classic, and it became more and more popular since Kylie Jenner wore it on Halloween a few years ago.

The easiest way to create this look is with a pink Barbie bodysuit and a pair of white boots.

15. Fairies

Has anyone noticed how the Winx fairies wore the cutest outfits? It’s impossible to not look hot in one of these outfits.

I love how each friend chose a color to go with, but still, they are pretty aesthetic when looked at as a whole.
