If you can't bear to be apart from your beloved this Christmas, then smother them with love – with a Twinsie.
Yes, following the phenomenon of the Onesie, couples who like to cuddle up while saving on fuel bills can share their body heat in a super-cosy all-over body bag built for two.
'The Twinsie' has three legs, four arms, two hoods and costs £50. The beast-with-two-backs garment is available in light grey, navy blue and aubergine.
Colin Leggatt, marketing director of The Original Factory Shop which created The Twinsie said: "It 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!"
However, there might be one drawback, as one wit offered on a message board: "What happens when one of you wants to pee?"
