I agree completely. Something that still looks 'cool' but is not 'thug wear.'
So that would be pants/jeans that are loose enough to not be skinny jeans or form fitting, but not hanging low either. The same thing with the shirts. Clothes that look heterosexual, non-bodybuilder, non-punk, not skin tight.
A lot of us would move on to more creative/wilder styles eventually, but it is nice to have something reassuring as a base to start from.
