True but just don't allow clothing like removing a hat or not, things like that we should consider it sin. It could be a sin of walking out of love if the greatest part of culture held to that custom and one shouldn't desire to want to provoke others intentionally. However much culture or most culture doesn't see the failing of doing these things is wrong. Immoral clothing styles however I'll get to in minute.
If one actually knows they're offending others it's best not to take one's liberty in doing so.
Actually I turn my hat around backwards in the summer (baseball cap) to keep the back of my neck from getting burned.
I'll agree with you on the pants hanging off the backside. That can be considered as immoral and I don't have to say why.
And there have been things that have ticked off people in every generation. The sixties saw bell bottom pants and tie dye shirts. In the decade of the 1920's there was different clothing styles which make people upset. They' weren't always immoral but just different. I remember the 1960s where the Beatles were thought of as long haired hippie's. John Lennon in later years did look straggly in his hair style but early 60's Beatles by today's standards they looked pretty normal. 1950s was basically short hair and brush cuts.
I agree though sometimes older generations had stronger morals BUT I wouldn't always equate a different clothing style or hair style as something which shouldn't be.
