You haven't found your Halloween 2025 costume yet, and you're looking for an original, stylish costume idea that won't break the bank?
There's no need to run to the stores to shine on Halloween night: your dressing room already contains everything you need to create a unique, ultra-stylish costume. This season, there's no need to invest in a costume you'll never wear again! By reusing your favorite clothes, like your chic black dress, your shell jewelry from this summer, or your red party dress, you can create a scary or glamorous look that's right on trend.
In this article, discover 6 ideas for trendy Halloween costumes in 2025, easy to reproduce with what you already have on hand. Haunted dolls, gargoyles, evil mermaids or black-and-white clowns... creative and stylish inspirations that combine fashion and thrills.
Looking for a cute and spooky Halloween costume? Then the Haunted Doll is the perfect choice! You can dress up in an elegant, cute and feminine Halloween outfit this year with this disguise.
What's more, it's easy to reproduce: if you already have a pretty babydoll dress in your wardrobe, you've got the basis of the look! You can just as easily wear a balloon dress, with puffed sleeves or ruffles. The main thing is that your dress should be in a pastel color: pink, blue, white or cream, and have a childlike or girly style.
To complete your haunted doll disguise, add a pair of lace tights, white pearl jewelry, ballet flats and any other romantic accessories, such as lace gloves, a pink headband, etc. To make a difference, customize a stuffed animal to make it more frightening: replace its eyes with buttons, for example, or sew on scars.
Here's our haunted doll Halloween costume inspiration to replicate this year:

Ever thought of dressing up as a gargoyle for Halloween ? This costume is easy to reproduce with the clothes you already own. Stand out from the crowd this year with your gargoyle disguise ! Inspired by mystical and slightly scary medieval statues, this outfit blends dark allure with intricate details for a unique look.
To create this look, start with a monochrome gray or silver outfit: a skirt, long-sleeved top and gray tights can serve as a base. Choose garments with draping effects and interesting textures to recall stone. Complete your costume with a pair of gray tall boots and snake jewelry.

Looking for a trendy Halloween costume that reuses your summer wardrobe pieces? Opt for the evil mermaid: an idea that's both glamorous and scary. This costume is inspired by legendary sea creatures, but revisited with a dark twist to match the Halloween mood.
The advantage of this costume is that you can reuse your crocheted or open-weave clothes from this summer, as well as your shell jewelry. A long flowing skirt or crocheted dress in shades of brown, green or pearly will do perfectly to recreate the bewitching silhouette of a mermaid. Then add a few nautical accessories like a shell necklace, a pearl belt or even a fishing net as a shawl.
To give your disguise an evil dimension, work the make-up with metallic hues: midnight blue, emerald green, silver or black. Graphic eyeliner, strategically placed glitter and a few brush-drawn scales will transform your look into a spectacular Halloween costume.

If you like glamorous yet mysterious costumes , the black angel is the perfect idea for Halloween. This costume plays on the contrast between angelic softness and dark allure for a result that's as chic as it is scary. What's more, it's easy to recreate from the basics in your wardrobe.
To adopt this costume, start with your favorite little black dress. It will be the basis of your outfit. Then add a pair of black lace tights or stockings for a subtle touch of glamour. Then slip on a pair of black high boots or pumps. Finish the look with jewelry in dark tones.
And don't forget the costume's centerpiece: black wings, which immediately transform a simple black outfit into a spectacular Halloween costume. You can buy them ready-made, or make your own with a few feathers and an elastic backstrap.

For a Halloween costume that's both fun and a little scary, the black and white clown is a perfect idea to create from pieces you already have in your wardrobe. Gone are the garish colors: here, make way for a chic, minimalist version of the classic clown costume, ideal if you like elegant monochrome looks.
Start with a black and white striped top, the main piece of the look. Pair it with a black ball skirt for a volume effect inspired by vintage circus costumes. To accentuate the graphic, theatrical aspect of the costume, add striped stockings, white gloves and a small clown cap or pointed hat to match. Don't hesitate to mix and match prints for an even more extravagant effect: stripes, polka dots, checks - let your creativity run wild! Diamond prints and checks are two of this season's major trends, which we presented in our last article "the 7 must-have fashion pieces for autumn 2025"
For an even more Halloween-like effect, you can play around with make-up: pale complexion, red or black lips, rosy cheeks and tears drawn in with black pencil to create a look that's both cute and spooky.
