I see nothing wrong with going a whole day with no clothes on in your own home. That is unless I do certain activities such as vacuuming, sweeping the balcony, taking hot food out of the oven, or deep frying, then it is important to wear clothes. I actually close and lock the bathroom door in case an intruder comes in I feel the extra locked door is an extra barrier of protection, that in addition to wearing underpants of course.
