What do you wear under a Morphsuit? For most people the honest answer is close-fitting underwear and not much else: the original Morphsuit is a single stretchy layer of 92% polyester and 8% elastane that fits like a second skin, so anything bulky underneath will show through. Snug boxers or briefs, a fitted vest if you want a base layer, and you are sorted. Get that first decision right and the rest is easy, but here are the dozen things you only really learn once you have actually worn one, from seeing out to drinking to picking your colour.

What to wear under a Morphsuit

The suit is built to be worn over as little as you are comfortable in, because the fabric is thin and stretchy on purpose: that second-skin fit is the whole look. The catch is that thick seams, waistbands, logos and pockets underneath will read straight through it, so keep whatever you wear flat and close-fitting. Plain boxers, briefs or a snug pair of shorts suit most people; a fitted base-layer top and leggings work if you would rather have a full layer between you and the suit, and they add a little warmth for a cold night. Skip belts, chunky waistbands and anything with hard fastenings, because you will feel them all evening.

The one thing nobody tells you: wear the underwear you would put on for the gym, not your going-out best. We cut every Morphsuit to a true-to-size, second-skin fit, so comfort underneath beats everything once you are in it for hours.

Can you see out and breathe in a Morphsuit?

Yes to both, and it is the part that surprises people most. You can see out through the mask panel, which we knit lighter than the body of the suit so it is easier to see through, while from the outside nobody can easily make out your face. It works a bit like a net curtain, letting light through one way far better than the other. Breathing is the same story, because the fabric is breathable by design, a 125GSM-plus knit built to move air rather than trap it, so you are not gasping behind a solid mask.

Two honest caveats we always give first-timers: depth perception softens a little, and going from a dark street into bright light (or the other way) takes a second to adjust. Give yourself that moment at the door and you will be completely fine.

Can you eat, drink and go to the loo in one?

You can drink without taking the whole thing off, which is the question we get asked most before a stag or hen do. The mask fabric is thin enough to sip through for a quick round; for a proper drink or any food, most people just roll the hood back off the face for a few minutes. The less glamorous bit is the loo. The original Morphsuit is a single piece that zips up the back, so you reach behind your neck, unzip and peel the top half down rather than trying to work around it.

Our advice, learned the hard way: sort that routine out early in the night rather than three drinks in, and go with a mate who can reach the zip.

Are Morphsuits hot? Staying comfortable all night

A Morphsuit is warmer than normal clothes because it covers you head to toe, but it is not the sauna people expect, because the fabric is breathable rather than a sealed rubber layer. In a warm, busy room you will feel it, so the trick is to dress for the venue and not the doorstep: go light underneath for a hot club, add a thin base layer for a cold October street, and pull the hood down when you need to cool your face.

This is where the fabric earns its place. We build every suit from 125GSM-plus breathable material and check each design against 30-plus measurements, which is what keeps it wearable across a full event instead of just the first hour.

Getting the fit right (and getting it on)

Getting into a Morphsuit for the first time is a small comedy: legs first, then arms, then the hood over your head, then a quick wrestle with the back zip. It goes far easier if you size right. We cut Morphsuits true to size and publish a size guide on every product page, set by height, so measure against that rather than guessing. Too small and it pulls at the shoulders and crotch; too big and it bags at the ankles and wrists and loses the clean second-skin look that makes the suit work.

This is the promise the wider category keeps breaking. Every design is checked against 30-plus measurements and put through part of our 500,000-plus quality checks a year, so the suit that turns up matches the size on the label. That is more than the see-through, one-size-fits-nobody stuff from no-brand sellers can say, and it is why what you see in the photo is what arrives.

Where a Morphsuit comes into its own

A Morphsuit is at its best when the whole group is in on it. A line of solid-colour suits reads as a team from across the room, which is why they are a staple of stag and hen dos, sports crowds, freshers' weeks and themed nights, and a reliable last-minute Halloween costume when you want fancy dress that needs no accessories. It is also a genuine icebreaker, because being anonymous makes most people a bit braver than usual.

There is a bit of history behind that. The original Morphsuit is the all-in-one spandex suit our founders launched in 2009 and sold 20,000 of in their first year, so it has had plenty of nights out to prove the point. If Halloween is your occasion, our guide to the best Halloween costumes has more group-friendly fancy dress ideas.

Picking your Morphsuit: colour and what's in the pack

When you are ready to get your own, the main decision is colour, and we make the solid Morphsuit across the full range.

The purple Morphsuit is a bold, easy all-rounder.

The silver Morphsuit catches the light and photographs brilliantly for a group; and there is pink, gold, white and plenty more in the solid-colour Morphsuits range if you are matching a theme.

What is in the pack is deliberately simple, and worth stating because the wider category loves a vague listing: you get the full-body adult Morphsuit, one piece, nothing to assemble. It ships tracked within 2 working days, so a last-minute plan still works. For the whole line, including patterns and character suits, start at the Morphsuits hub, and if you are completely new to the suit, our explainer on what a Morphsuit is covers the basics before you buy.

Frequently asked questions

What do you wear under a Morphsuit?

Close-fitting underwear, and not much else. The suit is a single stretchy layer of 92% polyester and 8% elastane that fits like a second skin, so bulky seams and waistbands show through. Snug boxers or briefs work for most people, with a fitted base layer if you want extra warmth for a cold night.

Can you see out of a Morphsuit?

Yes. The mask panel is knitted lighter than the body of the suit so it is easier to see through, while from the outside your face stays hidden. It works one way, like a net curtain, so give your eyes a second to adjust when you move between bright and dark.

Can you drink in a Morphsuit?

You can. The mask fabric is thin enough to sip a drink through for a quick round, and for a proper drink or any food you just roll the hood back off your face for a few minutes. The suit unzips down the back when you need it fully off.

Are Morphsuits hot to wear?

Warmer than normal clothes, because they cover you head to toe, but not the sauna people expect. The 125GSM-plus fabric is breathable rather than a sealed layer, so it moves air. Dress light underneath for a warm room, add a thin base layer for a cold street, and pull the hood down to cool off.
