Every man knows onesies aren't just the domain of women folk and children. In fact the biggest take up in onesies in the last year has been from men.
To be honest, what is not to like about the onesie. It's easy to wear (needs no thought), comfortable (we've been told men like a bit of space!) and allows you to show off a bit (especially in some of the novelty onesies).
We've spotted onesies on the likes of Mario Balotelli, Harry Styles and Justin Bieber, but they are not just the domain of the young pop sensation. Deputy PM Nick Clegg has said he likes to kick back in a Onesie as has former England Cricket Captain Michael Vaughan.
Onesies are the perfect gifting idea, so make sure to act soon as last year we heard that by December most stores had started to sell out.
