What do you sleep in...?

[Tilllly]

It's very warm, but still, I cannot bring myself to sleep naked

Though, if there were a fire, I would hopefully get rescued first, if I did 😁

Birthday suits have been default sleepwear for both of us since way before we met, in my case since I was about 10 and DH a similar age. They don't cost anything, are always available, wash well, don't get forgotten when we go on holiday and take up no luggace space when we fly with Ryanair. Most importantly, they are eminently comfortable, and while getting a bit wrinkled nowadays, we expect them to see us out for the rest of our days.
