People should do what they are comfortable with, but yes, if a guy wants to attract women, this is definitely a way to get what he wants.
I was part of the alternative scene and I also thought the goth-boy aesthetic was very attractive. All the girls did. To me, the most attractive thing a man could do to his appearance was to let his hair grow long. Like past the shoulders long.
Didn't have to put on make up and jewelry. Just have long hair and you could be fat or skinny, pretty or ugly. Didn't fucking matter. I'd look. If Henry Cavill walked down the street next to a nerdy guy with long hair, I would look at the nerd everytime. If he wore band t-shirts and military boots, it was game over. Only way a guy could fuck it up for himself with me was if he started the nice guy routine or was so socially awkward he couldn't talk to a girl. I have experienced both. The latter was a full date where the guy didn't say a word to me once and I was the one who had walked 20 km to get to his place because he had social anxiety and couldn't leave his home. Poor guy. I hope he's doing better today.
