Halloween in Cardiff 2026: What to Wear on a Night Out

Halloween lands on a Saturday this year, which in Cardiff means it doesn't land on one night at all. It starts on the Friday at The Globe and Depot, carries on through a Saturday afternoon at Y Plas, and finishes around four on Sunday morning at The Great Hall or District, depending on which kind of night you picked.

The clocks go back on Sunday 25 October, so by the 31st it's dark before five. Cardiff in October averages under 15°C by day and around 7 or 8°C overnight, with rain on about fourteen days of the month (that's the Met Office's long-run average for Bute Park). So whatever you wear has to get through the queue and the walk home as well as the party itself.

This is a guide to that problem, not a costume list. The idea is to wear your own clothes with one Halloween decision in them, so you're in the spirit at the door and still look like yourself at three in the morning.

Cardiff Halloween 2026: what's on, and what each listing says about dress

All of these are on their ticket pages as of mid-October. Where an organiser gives a dress code, it's quoted. Where they don't, I've said so rather than guessing.

• Friday 30 October: So Fetch, The Globe, Albany Road. A 2000s Halloween party, 11pm to 3am, last entry 2am, 18+. The listing says Mean Girls-inspired fancy dress is "highly encouraged".

• Friday 30 October: Shangri-La Halloween with Bullet Tooth, Depot, Curran Road. House, 8pm to 2am, 18+. Last entry is 9:30pm, which is early enough to matter. No dress code given.

• Saturday 31 October: CUE Halloween, Y Plas, Cardiff University Students' Union. A house day party across three rooms, 3pm to 10pm, with Locky, M-High and Saoirse among the DJs. No dress code listed.

• Saturday 31 October: CYNT Halloween with Notion, District, St Mary Street. House, garage and bass, 9pm to 4am, 18+. The listing says this will be District's last event before the venue closes.

• Saturday 31 October: Halloween Rave with Andy C, Sota and [IVY], The Great Hall, Cardiff University Students' Union. Drum and bass, 10pm to 4am, last entry midnight, 18+. "Fancy dress is strongly encouraged."

• Saturday 31 October: Living Dead Festival Halloween, Tramshed, Clare Road. House and disco across themed rooms, 10pm to 3am, 18+ with photo ID. The organisers' whole brief is "come dressed for the occasion".

• Saturday 31 October: Black Parade, The Globe. 2000s emo anthems, 10:30pm to 3am, last entry 1:30am, 18+. No dress code, though with My Chemical Romance on the playlist it hardly needs one.

Times and line-ups do change, so check the ticket page the week of. And look at those last-entry times. Depot closes the door at half nine on the Friday and The Great Hall at midnight on the Saturday, and an extra forty minutes on eyeliner is exactly how you end up on the wrong side of one.

The brief: one Halloween idea, not a full costume

Most of these listings ask for fancy dress in the encouraged sense, not the compulsory one, and that gap is the bit worth dressing for. A full costume is great until about 1am, when the wig is hot, the cape has been in someone's drink and you're wearing something you will never wear again.

So start from clothes you already like going out in, in a colour that reads as Halloween at a glance, and add one deliberate idea. Horns, say, or fake blood at the collar, or lace where you'd usually have cotton. Everyone at the door gets it, and on Sunday the dress goes back in the wardrobe instead of a bin bag.

Formula one: wear black, then add one detail

Black is the obvious base, and it's obvious for good reasons: it reads as Halloween in a dark room and takes whatever you put on top of it. A black mini dress is also one decision, which counts for a lot when you're getting ready in a shared bathroom.

Then do one thing to it. A veil, maybe, or a red lip pushed further than you'd normally push it. Just the one. The restraint is the subversive bit: you look like you came to a party, not like you came from a fancy-dress shop.

If you'd rather not do a dress, the same rule works as separates. A black going-out top or a lace one over a faux leather mini skirt does the job, and every piece of it works again for Christmas.

Formula two: a check mini for the emo night at The Globe

Black Parade is the one night on this list where the playlist is the dress code. 2000s emo had a uniform and nobody has forgotten it: check, black, and a studded belt doing nothing structural. Halloween is the one night a year you can wear all of it without explaining yourself.

To do it without looking like a 2006 shop window, take one piece seriously. A check mini skirt with black tights and a plain black top is a whole look already. Add more eyeliner than strictly necessary and leave it there.

The Globe is on Albany Road in Roath, the best part of half an hour on foot from St Mary Street, so dress for the walk as much as for the room. The jacket and boots further down are there for exactly this.

Formula three: pink for So Fetch

So Fetch asks for Mean Girls, which makes it the easiest brief in Cardiff this year. It's pink. You don't need a Burn Book prop or a mouse costume to get the reference across; a pink top or a pink mini dress does it, and anyone who's seen the film works it out in a second.

Sequins are where it tips from 'nice pink top' into something that reads as a costume from across the room, so go there if you want the nod to land at a glance. It's also a Friday, which means it's a night you can wear the sequins and still have the Saturday free for something darker.

Formula four: a red mini dress for everywhere else

For Living Dead at Tramshed, where the brief is just to come dressed for the occasion, or The Great Hall, where fancy dress is encouraged and nobody's checking, red says Halloween without spelling it out. A red mini can be a devil, a vampire, or just the person who made the most effort, depending on what you put on your head.

With black tights and black boots it stops being a party dress and starts being a costume. Take the horns off and it goes straight back to being a party dress, which is handy by Caroline Street at three.

What to wear for the queue, the rain and the walk home

It's dark from five, it's single figures by the time you're queuing, and October brings rain on roughly every other day. Most of the nights above finish somewhere between two and four in the morning.

Cloakrooms help, but a cloakroom queue at 3am is its own small Halloween horror. A black jacket you're happy to keep on all night is the neater answer. Faux leather goes with every formula on this page and copes with drizzle better than wool does.

Then the shoes. The Great Hall rave runs six hours and Tramshed five, and from St Mary Street it's a good twenty minutes or more on foot to Cathays and longer to Roath. A black boot with a flat or block sole goes with every idea here and gets you home with your shoes still on your feet.

Keep the bag on your body, too. Phone, card and ID go in it (every late-night listing above is 18+, and Tramshed spells out photo ID), plus whatever lipstick the look depends on.

More Cardiff edits

Going to the CUE day party at Y Plas? The Cardiff Bay day-party edit deals with wearing one outfit from afternoon into night, and the Cardiff freshers edit covers the bag and walk-home questions for Cathays nights. If the gothic side of this is your favourite bit, the Charli XCX gothic glamour guide takes black further than Halloween does, and the first cold snap edit sorts out the proper winter coat.

Prices and sizes in the rails above change week to week, and the last fortnight of October is when everyone else is shopping for the same night. Don't leave it until the Thursday.
