I have no idea about fashion but here are my observations. I don't even know if these things have necessarily ever gone "out of style", so to speak, but I think they're making a comeback.
  1. Choker necklaces
  2. Turtlenecks
  3. Scrunchies
  4. Plain t-shirts
  5. High waisted jeans
  6. Natural hair
  7. Coloured eye shadow
