I get my Fashion Report news from Meoni's Fashion Report Friday on Youtube. these aren't really guides just... glamour posts. There's also a Fashion Report Reddit thread.
Meoni started to add dyes to his reports just last week and I tend to forget about this unless I can get 100 so...
Weapon: Honey Yellow
Helm: Nomad's Cap of Casting
Body: New world Jacket is gold but I just dyed by Anemos Jacket Opo Opo Brown
Nails in the Coffin: False Nails or Claws of the Beast (Blood Red)
Trousers: Toadskin Culottes (Soot Black) (not one of the four but you should wear bottoms regardless!
Shoes: Toadskin Workbooks (any similar model seems to do) Opo Opo Brown
I just dyed everything I could really.
