I guess it depends on ones interpretation of the style, and their knowledge of the style. Most commonly the scene look is associated one of two ways.
The most well-known is the look of younger Audrey Kitching - back when she was doing things like Trashy Life. The ripped-up leggings/tights, with tutu skirts and crazy colored bright hair with tons and tons of extensions.
Audrey and Zui Suicide (Trashy Life)
Though the most common look, and that worn by most ‘everyday’ scene girls, was that of people like Bel Stardust, Brittany Kramer, Katie Babyfayce, Aida Kamikaze, and people like that. The look mainly focused on the hair - which had to be huge. 80s Hair metal icons were very popular inspirations for scene hair, people such as Nikki Sixx from Motley Crue.
Wow, I’m turning this into an essay answer. Basically the look of scene was/is big hair, lots of eyeliner, and intentionally tacky jewellery. It stems for a combination of 80s America, and current Japanese Harajuku fashion with other elements of various styles as well. Things that were/are popular include: piercings (especially septum piercings due to being popularized by Audrey and many other ‘scene queens’), Sidekick phones (All the major scene queens had one - Audrey, HannaBeth, Jac, Zui, Melissa Marie), cats eye eyeliner, bright pieces randomly dyed into your hair, razor-cut layers in your hair, fishnet stockings, or stockings with holes torn in them, big hair bows, coontails dyed in your hair, and bright pink blush.
Thank-you so much :3
The most common haircut for shoulder-length scene hair is a Japanese-style rocker-mullet type hairstyle like this:
Or, alternatively, to just tease the short length then add extensions.
Hope this helps.
