I wear an oversized t-shirt with just a pair of Bridget Jones pants topped with a 10.5 duvet the cover is teddy fleece as is the fitted bottom sheet I bought these last year and they keep me cosy all night so much so that I bought 2 x extra sets.
Would you rather stay your current age or swap the digits around?

I'm another wimp here. No heating on through the night so I wear .... Wait for it .... Socks, sleeveless vest, Fleecy PJ's, sometimes a dressing gown over that. A hot water bottle, two, yes two duvets and sometimes I will still put a fleecy blanket over my shoulders. Then 'sometimes' in the middle of the night, half of it comes off as I'm too warm.
