20, of course.

1-5 depending on local conditions

20

20, for over a decade. However, in the last six months I found a carpet beetle larvae on my duvet so since then it's been what I'd imagine to be 0; thick hoodie, sweatpants, socks, no duvet. I hate bugs. I can't understand where the larvae came from. I have found maybe two a week since then in my carpets but it doesn't seem to be a big infestation? None of my clothes or fabrics have holes in them. I've washed everything and hoovered like a madman. They don't seem to be infesting anything in my apartment. I think they must live in the floorboards or something. God I hate bugs.

17 exclusively.

No long sleeves here. Well i guess 22? Long sleeves and shorts.

20 I guess. The underwear I normally wear isn't listed on the graph. Jockstrap and no shirt baby

Lol who sleeps with a bra on when they have a choice?

Well OP apparently

20 when I can get away with it, 17 the rest of the time.

4 in Summer, 1 in Winter but with a hoodie. I'd wear a hoodie in Summer if I could find tees with hoods. I dislike drafts on my neck and shoulders.

15

Somewhere between 16 and 20. I sleep hot.

I where the same thing I walk around in during the day. I don't bother changing.

19

huh, no socks listed? I'm usually either 20 or 19, but sometimes during the winter I'll sleep in my thigh highs as well.

18

For 40++ years : #20. Would not have it any other way.

Sleeping in a bra? Where's the option to shackle myself to the bed as well?

Since becoming disabled 5 because it's too hard for me to pull up my pants after peeing. And it would be too much hassle to always call over my wife or a caretaker to pull them up when I'm laying in bed all day anyways.

On hot days I might ditch the t-shirt.

21, a sleeveless nightgown, panties optional. No bra, because I'm not in a vampire movie

somewher between 18 and 20, summer and winter.

I did do #1 on a winter camping trip in our campervan this winter just gone, but it did get down to ~-7 C and campers are not that warm

1 - in winter 3, 7 or 18 - any other time of the year

20

Are those pajama pants, or long johns? May not seem like it matters, but there's a huge difference in their purpose.
