contributed to the original punk sound and aesthetic. Because the original subculture meant to challenge to the mainstream, and punk movement became major it was brought to the mainstream. If punk is commercialized, it is far from street culture. This is the paradox of punk; as a subculture, it must always be evolving to stay out of the mainstream. Punk Girls written by Liz Ham is a photo-book featuring 100 portraits of Australian women in the punk subculture, and it was published in 2017 by Manuscript Daily. Discrimination against punk subculture is explored with her photographs in the book; these girls who are not mainstream, but "beautiful and talented". Interactions with other subcultures Some of the first hip hop MCs called themselves punk rockers, and some punk fashions have found their way into hip hop dress and vice versa. Malcolm McLaren played roles in introducing both punk and hip hop to the United Kingdom.

Conversely, ska and reggae, popular among traditionalist skinheads, has influenced several punk musicians. Punks and skinheads have had both antagonistic and friendly relationships, depending on the social circumstances, time period, and geographic location.
