We know, we know, what with all those theories about what makes the perfect relationship, it's a bit hard to keep up.
First there's having sex on the first date, watching TV in bed, then going on date nights.
Well now we're ready to thrown a new one into the mix, because a new study suggests sleeping in the buff is the way forward.
The poll of over 1,000 people showed 57% of Brits sleeping in the nude said they were happy in their relationships.
Meanwhile, only 47% of couples sleeping in their pyjamas said they were happy. And, utterly unsurprisingly, only 38% of onesie-wearers.
Stephanie Thiers-Ratcliffe, of Cotton USA, who carried out the poll, explained: "Bedding can feel extremely soft against the skin, encouraging openness and intimacy between couples and ultimately increasing happiness."
So there you have it. Get your kit off and all will be solved.
