And relax... nine best onesies for adults

The cold snap is coming. We say stay on the sofa, preferably wearing one of these cosy onesies

1. Kigu lemur

Japan are really to blame for all of this - they've been doing the onsie thing for years. They call em' kigurumi, translated as 'costumed animal character'. Kigu started importing them in 2009 and their fun unisex designs are still made in Japan now. Choose from unicorns to kangaroos (complete with joey in its pouch). The lemur's a new addition to the collection. We particularly like the tail, but you can tuck it into the back of the Kigu if you're worried it'll get in the way.

£39.99 www.kigu.co.uk

2. Asos onesie with shooting patches

For blokes who are dubious of wearing something quite so well, relaxed, this this grey one-piece has a nod to fashion (shoulder patches are very autumn-winter 2013, don't you know?). The cotton mix fabric keeps it soft and comfy.

£32 www.asos.com

3. OnePiece Jeansy Onesie Washed Navy

From the Norwegian brand credited with starting onesie-mania, this navy number with jean-style detailing is at the less slouchy end of the spectrum. The drawstring means you can nip it at the waist for a bit more structure. You could almost wear it out. Almost.

£139 www.onepiece.com

4. Boohoo fairisle

If there's such a thing as a classic onesie print, then fairisle comes to mind. This one's really soft, good value and super-slouchy for those planning on indulging in one too many Quality Streets this Christmas.

£25.00 Boohoo.com

5. The all-in-one-company's create-your-own onesie

There are plenty of bonkers onesie designs out there but the all-in-one company let you take it one step further and create your own. You can let your imagination run wild; there's a hundred fabrics to choose from and you can add on ears, tails, feet, pockets and mittens - and a personalised message too. The mind boggles.

From £48.99 for adults. www.the-all-in-one-company.co.uk

6. Next faux fur snood black all-in-one

For those not quite ready to ditch the glamour completely, this slimmer fit all-black fleecy number comes with a faux fur collar. It's the Elizabeth Taylor of the onesie world, if you will.

£46 www.next.co.uk

7. Jigsaw cashmere onesie

Haven't you heard, a cashmere onesie is this season's must have luxury item!? (Well, if you've got some spare notes lying around.) Jigsaw's super-soft, fine-knit grey one is as indulgent as they come.

www.jigsaw-online.com £295

8. FGL Colour Real Stripe Onesie

The online underwear specialist has made a foray into one-pieces. This bright stripey number has a bit of a pajama-y feel with buttons instead of a zip.

www.figleaves.com £28.80

9. F&F Santa Onesie

This list wouldn't be complete without a sprinkling of Christmas cheer. This Santa one-piece from Tesco comes with a beard and hat - go from lolling on the sofa to dishing out the family's presents without changing your outfit. Win, win.
