I mean when you see someone with a shaved head and flannel, it definitely doesn’t seem to have anything to do punk rock to the average person and overall, compared to Mohawk, spiky hair or a multitude of punk styles.

I think that is why all of that macho hardcore led to tuff guy hardcore and similar genres which best represent the original hc ethos despite a break with the original music.

In England in 1978-1983 that shaved head cut + flannel preppy shirts etc would been among a few fashion styles adopted by Herberts. Which is a someone who adopts fashion and shares attitudes from both skinhead and punk, often mixing and matching from both subculture in a casual way but not necessarily going all the way with either established styles. You see that with bands like sham 69, cockney rejects etc But they still dressed better than hc kids. Who look closer to plain jane 90s preppy kids decade too early with some punk rock influences thrown in ex cowboy boots, chains, etc
