Fans say it’s fantastic to wear on top of pyjamas for an extra cosy layer, plus they praise it for staying just as fluffy when washed. One reviewer even noted it’s so cosy they don’t need to put the heating on - the ultimate praise when energy bills are soaring. 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 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. Look at the sleeves and ankles of your onesie. Many come with elasticated cuffs to keep you warm, but if you think you’ll find that annoying, opt for a looser fit onesie. 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.
