Congratulations! We could at least talk to one another and have something in common. The human body is a precious gift from God, our Creator. It should always be treated with the dignity and respect befitting such a gift, so respectful and tasteful dress is always in order, not only in public or for formal or important occasions, but in private as well. Dress does influence behavior-- see the 1956 Warner Bros. short Bugs Bonnets.
Besides, jeans, sneakers, sweat pants, shorts, miniskirts, and the like are just too cultural for a hopelessly countercultural person such as me-- but you probably realized that by now.
In fact, if you've come this far, you're probably the only one left (except for those who fibbed to see what's here). Still, you might want to consider the remaining questions.
