I'm looking at costumes used by Punk-Rock Bands, to get an idea of how they would usually dress. I'm going to look mainly at American Punk Rock, as my group originates from the United States.
These two bands appear to dress almost entirely in black. Most of the members have messy hair and dress in smart-Casual wear. Many members have tatoos, whether small, or covering the majority of their arm. It shows the band members as perhaps being quite carefree and laid back.
These Punk-Rock bands are dressed much more casually, many just wearing casual shirts, or T-Shirts, and being represented in rather different ways to one another- Like completely different characters. It represents their individualism, that they're not all just band members. They have their own personalities.
I will likely ask my actors to wear Smart-Casual wear. I will request they make their hair look messy, and that they wear a black T-Shirt, or perhaps a shirt with a Checked pattern.
