Adult costumes for men, women, couples, and groups

Our men's costumes run from wrestling and superhero looks to classic characters, while the women's costumes stretch from Disney favourites to 1920s decade sets. Going as a pair or a whole squad? The couples costumes and group costumes pages are built for exactly that. And if the kids want in on it, the full costumes range covers them too.

The John Cena WWE Costume for Men puts the Cenation leader's whole ring look into one set: a muscle-padded top, shorts, a hat, wrist cuffs, and a "Never Give Up" towel. It runs from Small to XX-Large, sized by chest and waist.

Fancy being Elsa for the night? The Women's Disney Elsa Frozen Travelling Classic Costume recreates her look from the film in a single dress, with nothing extra to keep track of. It comes in one size, Medium, so check the size guide before you order.

How to choose an adult costume

Our adult range falls into four broad formats, and each one brings something different to the night. A full-body Morphsuit gives you the whole look in a single stretch piece, while a standard dress-up costume builds it from real garments. A piggyback costume brings the joke with it, so the group photo takes care of itself, and an inflatable gets you spotted from across the room. Go with whichever suits you and the occasion. Here's one of each.

First up, the full-body format. The Green Alien Morphsuit covers you head to toe in stretch fabric, with double zips and reinforced stitching at the stress points. It's sized by height and weight against our size guide, from Medium (5'5"-5'10") up to XXL (5'10"-6'5").

For a full outfit built from real garments, the Womens 20s Charleston Flapper Costume comes as a complete 1920s set: a fringed velour dress, a feathered diamante headpiece, and elbow-length gloves. It comes in Small, Medium, and Large: check the size guide on the product page for your fit.

Then there's the piggyback. The Bearded Bavarian Piggyback Costume creates the illusion of being carried by a bearded local, with built-in mock legs you stuff yourself with towels or newspaper. One size fits most adults from 5'4" to 6'4", and the drawstring waist adjusts to suit.

And finally, the inflatable. The Avocado Inflatable Costume stays puffed up for over 4 hours on a built-in fan (4 x AA batteries, not included), and there's a pocket for your phone. It's one size and fits most adults.

Getting the size right

Fit is where we get serious. Every costume goes through over 30 measurement checks. Most adult costumes are sized like everyday clothing, from Small through to XX-Large, with a size chart on every product page for chest, waist, or UK dress size.

Morphsuits work a little differently. Each one is a single stretch piece rather than separate garments, so we size them by height and weight against our size guide chart, from Medium (5'5"-5'10", under 160lb) up to XXL (up to 6'5", under 250lb). Piggyback and inflatable costumes are usually one size, built to fit a wide range of adult heights and builds. For more sizes and styles, browse the full adult Morphsuits range.

Frequently asked questions

What counts as an adult costume?

In our range, adult costumes cover full-body Morphsuits, standard dress-up outfits, piggyback costumes, and inflatables. They're sized from Small through XX-Large or, for Morphsuits, by height and weight against the size guide.

Are Morphsuits classed as adult costumes?

Yes. A Morphsuit is a full-body adult costume made as a single stretch piece, so we size it by height and weight against our size guide chart instead of by chest or waist.

Can adult costumes be worn for anything other than Halloween?

Yes, all year round. Parties, stag and hen dos, sports days, and fancy dress nights are all good reasons to get yours back out of the wardrobe.

What sizes do adult costumes come in?

Standard dress-up costumes usually run from Small to XX-Large or by UK dress size, while piggybacks and inflatables are typically one size fits most. Morphsuits go by height and weight instead. Whichever style you pick, check the size guide on its product page before you order.

Do adult costumes come with accessories included?

Many do. The John Cena WWE costume above comes with the top, shorts, hat, wrist cuffs, and towel in one set. Others, like the Morphsuit, are designed as a single piece with no separate accessories at all, so it's worth checking what's included on each product page.
