I understand everyone has the Right to express themselves as they wish, but since one's appearance conveys a certain message, one should consider what message their style of dress conveys.
If I want to present myself as a punk of some sort, I would probably put on really baggy, sagging pants that keep trying to fall off and look like I'm carrying the results of a "tactical drop". If I want to pass myself off as an artsy-type guy, I'd probably dress in some kind of colorful silk vest (I think that's the new trend). If I choose to present myself as a rugged individual, I may choose to dress in a worn get-up (maybe like Wolverine?:lol
.
The manner in which you dress is the manner in which you wish to be perceived: dress like a punk to be thought of as a punk, dress in a suit to be thought of as a lawyer-type, dress in a kilt to be seen as a Scotsman (I've kilts on my mind, and I will be buying one in the near future).
Why did the Civil Rights movement begin with Rosa Parks and not with other individuals discriminated against on the buses? Besides age (equated to maturity, on could argue), she dressed in a way that conveyed "harmless, law-abiding, little old lady".
