I’ve never really understand the appeal of the onesie. People argue that it’s comfortable, that it makes them feel relaxed, that it keeps them really warm. But what’s relaxing and warm about stripping half naked every time you visit the loo? And who can be bothered with all that faffing around?

Clearly, people aren’t deterred by fiddly zips and chilly bathroom trips, because Marks & Spencer has just released a £199 luxury version – in chic cashmere, presumably to minimise the ‘babygro’ factor.

Think I’ll stick to my slanket.
