A Halloween costume that is actually comfy

The fiddly outfit you can barely sit down in is the worst part of October 31st. Our take is the opposite: a soft one-piece you pull on, zip up the front, and forget about for the rest of the night. You can move, dance, hand out sweets at the door and flop on the sofa for the scary film without a single wardrobe mishap.

Because it's one piece, there's no fuss with layers, pins or props that go missing halfway through the party. You stay warm on a cold autumn evening, you stay comfortable, and you still look like you made an effort. That's the whole idea behind this collection: a costume you genuinely want to keep wearing once the trick-or-treating is done. A onesie-style outfit also suits anyone who finds the usual fancy dress a faff. There's nothing to assemble and nothing to keep adjusting, just one cosy layer that does the whole job from the doorstep to the after-party.

Super-soft teddy fleece in brown, grey and pink

Every style here is cut from our super-soft teddy fleece. People describe pulling one on as feeling like getting a giant hug, and that's about right. The fabric has a gentle stretch so it moves with you, and it's brushed soft enough to double as your cosiest loungewear long after Halloween.

There are three colours to choose from: a classic brown teddy, a soft grey, and a warm pink. The Women's Brown Teddy Bear Onesie, Men's Grey Teddy Bear Onesie and Kids' Pink Teddy Bear Onesie give you a sense of the range, and because the same colours run across women's, men's and kids', it's easy to put a coordinated look together. The fleece is 100% polyester, and several styles are made from 100% recycled polyester, so the snuggly feel doesn't cost the earth.

A matching Halloween costume for the whole family

This is where a one-piece really earns its keep. Pick a colour and dress everyone in it, parents, kids and the brave adult who said they wouldn't join in. Couples can twin in matching brown or grey, friends can turn up to the party as a matching crew, and the whole household can pose for the kind of photo you actually want to keep. It works for a doorstep full of trick-or-treaters and for a low-key night in with takeaway and a horror double bill.

Mix and match is just as good: a brown teddy here, a grey one there, a pink one for the youngest. Because each colour comes in women's, men's and kids' versions, you're not hunting around for something that almost coordinates. It all simply goes together, which is half the fun and none of the stress.

Fit and sizing

These are a regular fit, so the simplest rule is to pick the size you'd normally wear. If you're caught between two sizes, size up: there's a little more room to layer something warm underneath, and a relaxed fit is exactly what you want in a onesie anyway.

For a sense of scale, our 170 cm model wears a size S (UK 34–36), our 185 cm model wears an M (UK 38–40), and a child model of 129 cm wears 6–8Y. Use those as a guide alongside your usual size and you'll land in the right place.

Easy care that keeps the fleece soft

Looking after the teddy fleece is genuinely easy. Machine wash it gently at a maximum of 30°, turn it inside out first, and wash it with similar colours. Skip the tumble dryer, the iron, the bleach and the dry cleaning, and the soft, brushed finish stays exactly as snuggly as the day it arrived, ready for next Halloween and every cosy night in between.
