lol Civilized men don't wear polo shirts and jeans. Civilized men who like shirts and jeans wear polo shirts and jeans.
Fashion evolves and changes every decade. There's nothing wrong with wearing a hoodie, or having a chain with lots of diamonds, etc. in it. There was once upon a time where if a guy wasn't wearing a shirt and a tie when he picked up a girl to take her out, he wasn't a decent young man.
Now I will say however that there is definitely a time and a place for everything. Going to work with flashy jewelry and your pants hanging below the waste is unacceptable. Expression is fine, but self expression as an individual has to have it's boundaries. Especially when you are in an enviornment where you may be seen as a person representing a company, group, organization, etc.
It's not really a hip hop thing. It's just a thing. There are people who don't listen to hip hop that dress a certain way just because it's what's in style.
"Rockers" often wear there clothes below the waste, pierce anything that can be pierced, tattoo there bodies wherever they don't have a piercing and color their hair in all types of colors. They're almost exactly like the hip hop kids. Though as long as there's nothing offensive viewed on their clothing and such, then no harm done.
"Country" guys like to sport open shirts with tight fitting jeans with open shirts and cowboy hats. Spurs on their boots.
"Goth kids" well....you know what they look like. Dead ppl =p
It's just really a matter of knowing where the boundaries are and how respectful your language is towards those whom you may speak to. While it's fine to not really agree with a particular trend, style, etc. It doesn't mean that it isn't civilized. It just means that it doesn't fit in YOUR particular area of civilization. Or if it does, maybe you don't fit in there =p
Sex without the e is still SX!
