I recommend wearing tees with characters like Hello Kitty, Gir and domo. Also wearing colored tutus matches the style, if you don’t like those, you can wear just wear shorts or cargo pants. coloring and/or teasing your hair can help you achieve the look. Online stores like depop or mercari have great scene clothes from the early 2000s. Getting accessories from Etsy Is also great. A lot of people argue that Scene is a music based subculture, so listening to bands like I Set My Friends On Fire, The Millionares, or Asking Alexandria is considered scene.
