Because they would come in and out of your room unexpectedly and it would be weird. It isn't "normal" to sleep naked in a lot of countries, it is considered promiscuous. Of course, I don't agree but that's the truth.

Exactly!!
Especially my dad and big brother, they always come in to my bedroom without permission.
I can't forbid them to come since my room are like convenient store to them, they come to borrow stuff like a hair comb,or checking their appearance on mirror (my room have a big mirror) or writing tool, or sometimes asking for help about something that only me can do it. And they doing it without knocking first.

Lucky you, In my country Indonesia, they would think that a strange thing.
Even when you going out wearing a cloth that expose some of your body part, they will look at you with a disgust eyes or whispering behind your back.
Well there are some people that can accept it but most of them can't coz they are just so close minded.

Well be proud of yourself your not strange or anything and if people wistpering let them be it's not confortable but it's better than restrict yourself, anywhere you will go there are people who will look at you with disgust eyes and will insult you for what you are believe it I have hard time too ╥﹏╥ for other reasons ╮( ̄▽ ̄)╭

Well for me it's the fact that I have weak health since ever for no particular reason so I had hard time socializing with people it's like that now too and I had for 3 year a sport teacher who harassed and insulted me because I wasn't able to do things because of my health because of all of that I started to hate myself .... ╥﹏╥ and now I'm trying to recover from these years ╮( ̄▽ ̄)╭
Well, wearing a bra all day are hell.
ANd Sensei you wear it at home even when you go to sleep.
I, a girl really don't like wearing a bra and I prefer to sleep naked but I live with my parent and brother so I can't do it.
IF only I live in a foreign country.
