If it’s a thinner onesie, most people tend to just wear underwear underneath, but if you’re planning to wear clothes under your onesie to keep warm at home, remember to size up. Touching on the price of this, it is the most expensive in our edit, but for a luxury treat that you’ll treasure all winter long, we think it can be justified. As Money Saving Expert Martin Lewis keeps saying, it’s easier to heat the person than to heat the home, and wrapping up in a onesie when you’re the only one home is more cost-effective than blasting out the heating. Secondly, think about whether you want to wear pyjamas or thermals underneath your onesie, or just underwear. If you plan to wear clothes underneath it, size up.

Our favourite features?

The zip reaches to just below the belly button, so this is easy to step in and out of, plus it has ankle cuffs to ensure you feel extra cosy. It has a snuggly hood too. Our favourite features?

Love it or loathe it, winter is here, and with it comes cosy evenings in, and mornings snuggled up at home - and what better to wear for those comfy occasions than a soft, fluffy onesie?

As Martin Lewis said, it’s easier to heat the person than the home, so if you’re home alone during the day, rather than spending money heating the whole house, it’s worth layering up in a onesie to conserve warmth.

Recommendations from real parents The Hush Elle Supersoft Henley onesie gets our vote. It’s chic, comfortable and stylish enough to wear on video calls, without your colleagues knowing you’re in loungewear.

Firstly, do you want a hood? Many onesies come with novelty hoods with ears, while others have a simple hood. A hood makes your onesie extra warm and snuggly, though it does look more casual if you’re planning to wear it to keep warm while working from home. Reviewers commented that it is super fluffy, so watch out on first wear, as you’ll likely have fluffy bits around the house. The hood is good for chilly evenings too, and it’s easy to slip on and off, with a zip that reaches to the hips. Proving that onesies can be stylish as well as snuggly, this super-soft jersey onesie is the ultimate in luxury loungewear. The drawstring waist means it looks a little smarter than your average onesie, but is still super comfortable when you fancy a really lazy day. It has cuffed legs to trap the warmth in, and is roomy, with reviewers saying a small is perfect for a size 12, though they do note that it’s not very long, so maybe not the best onesie if you’re tall.
