According to Hebdige, what is a major factor that separates the mass culture from subcultures?

Style is a major factor that separates the mass culture from subcultures. According to the mass culture, there is one definition of style, but the truth is, it's a relative term. A common object used by the mass culture in the way that the creator intended, can take on a completely different definition when used by a subculture, thus changing the definition of style.
