Usually I sleep fully dressed o_o (and no, I'm not talking about changing into pajamas, I'm too lazy for that. I go to bed with the clothes I have worn during the day.) I am so cold all the time so socks is a necessity if I shall be able to fall asleep, otherwise I will just lie there and freeze all night xD
Only during the most hot days of summer will I go as far as to kick off my socks. :p Usually when it becomes warmer the clothes fall off in the order of pants, shirt and lastly socks. The socks might be off a couple of weeks per year max. Though even if there is a super hot summer, I tend to have socks on me most of the time. My feet are too sensitive and freezy D:
