I think it depends on what time of the year it is. The year has different weather patterns, so i guess every month has it's way of dressing according to me. During the cold months or during winter as you make call it, shorts are the last thing on my mind. Sometimes it gets so cold, and all you want to do is put on clothes that are warm enough so that you don't catch a cold. I always feel shorts are meant for summer times, and they are meant for the outdoors not sleeping with. We are advised that when you go to sleep, your body is supposed to be relaxed, you should not have on anything that is tight, or wear something with a collar or a belt that could easily chock you while you sleep. So when i think of shorts, first and foremost they will have a band at the waist or a string or are they called straps for lack of a better word, which can cause trouble while sleeping. When you turn in your sleep, that strap can open then it coils around your body, and could cause you harm. A long flowing light dress or a short dress is good enough to wear at night, or better still have nothing on and just wrap your soft blanket around you it's a nice feeling you also give your body a breathe of fresh air. Shorts are good when your out, at the beach or taking a long summer drive, and other outdoor activities. they are light and very convenient.
