I see... so why should one have to wear anything at all?
If I were to decide to go to work wearing just my hat and a pair of sneakers, why shouldn't I be allowed to do so?
Is showing one's behind or one's front bad taste? Or why else is it banned?
Who decided that --as outer garment-- shorts and XXL T-shirts are OK at work, but tight speedos are not OK at work?
Why are man allowed to run on the street in shorts only, barechested, but women aren't?
(at least that's what I've observed in most anglophone countries... other places around the world seem to have other, quite varying, rules)
