For the couple who do everything together
A Burnley company is hoping to double the appeal of the onesie with an outfit for two called the 'twinsie'.
The Original Factory Shop's invention has three legs, four arms, two hoods and costs £50, reports the Daily Mail.
The unusual garment is available in light grey, navy blue and aubergine and was apparently created after public consultation on Facebook.
Marketing director Colin Leggat said: "The Twinsie offers a practical but fun solution for those wanting to stay warm this winter without running up costly energy bills.
"And what a fantastic Christmas present for the person in your life, or even the person you'd like to get closest to!"
