Last-Minute Halloween Costumes You Can Throw Together Tonight


Forgot Halloween was today? Don’t panic. Whether you’ve left it until the literal last second or had a spontaneous invite pop up, you don’t need to fork out for a costume. These easy Halloween outfit ideas use pieces you probably already own – so you can still look the part, even if you’re on a student budget and a tight schedule.

🖤 Wednesday Addams

If you’ve got a black dress and a severe middle parting, you’ve basically got yourself a Wednesday Addams costume. Bonus points if the dress has a white collar, but if not, just layer a white shirt underneath and you’re good to go. Braids, pale makeup, and your best unimpressed face will finish the look.

It’s simple, instantly recognisable, and has that spooky-but-stylish aesthetic that somehow always works. Just add some chunky boots and sulky vibes.

🤠 Cowgirl

Yeehaw energy is easy to channel. All you need is a checked shirt or denim jacket, some jeans or cut-offs, and ideally, a pair of boots. Add a hat if you’ve got one – or improvise with a bandana tied around your neck for extra western flair.

Add a bit of bronzer, tousle your hair, and maybe draw on some fake freckles for the full rodeo-ready effect. Effortless and fun – especially if you want to dance all night without a costume getting in the way.

💿 Y2K Popstar

Think shiny, sparkly, and a little bit chaotic – and you’ve nailed the Y2K popstar vibe. Dig out your most OTT top (metallics, mesh, halter necks – all fair game), some flared jeans or a mini skirt, and sunglasses you probably wore to a festival.

Add space buns or a zig-zag hair parting if you dare, and load up on lip gloss and body glitter. Channel your inner Britney, Christina or early-2000s girl group energy and go full nostalgic diva.

🐱 Black Cat

Possibly the easiest Halloween look of all time – and still a classic. All-black outfit? Check. Eyeliner? Check. Just draw on a little nose and whiskers, pop your hair into space buns for a “cat ears” effect, and boom: you’re a black cat.

You can even turn this into a duo or group costume with different animals – just change the makeup details. Bonus: zero prep, and you’ll still look cute.

🧛 Vampire (Red Lippy + Eyeliner)

If you’ve got red lipstick and black eyeliner, you’ve got a vampire costume. Smudge a little red lipstick at the corner of your mouth for a blood-drip effect, create dramatic eyes with a smoky liner, and wear something dark or gothic – even just a black top and trousers will do.

Add a slicked-back ponytail or go big with waves, depending on your vibe. You can look as glam or as scary as you like – this is a versatile classic that works with whatever you’ve got to hand.

👻 Final Tip

“Halloween is about having fun – not perfection. So even if you’ve thrown it together in five minutes, you’ve nailed the brief.”

And let’s be honest – some of the best costumes are the ones you didn’t overthink. Keep it chill, keep it creative, and enjoy the night.
