If someone is somehow made uncomfortable by something as simple as "people tend to wear less but also more loose clothing going to sleep because it's more comfortable", then I seriously, seriously would recommend they get therapy, because that is a very simple, basic fact that isn't even dirty or anything like that, nor does it have the slightest sexual connotation. Like, if you've ever visited a friend or family member early in the morning, and they get up for breakfast before getting changed out of their bed clothes, you'll probably notice they either aren't wearing much, or put on a snug dressing robe to cover themselves up before getting dressed proper. There is absolutely NOTHING to be uncomfortable about or triggered by there. Unless, I dunno, you met someone who had a demon dressing robe that threatened to eat you or something. :V
