Ahri skin

Sorry but when it comes to skins, lore doesn't matter, a clear example is Justicar Syndra or Heartseeker Varus, or Arclight Vayne (eventhough she fights the evil in both situations, she clearly would never wear those shiny clothes, she hunts evil at nights, those clothes would definitely reveal her, and even if she worked on day she would never choose such clothes, she seems to like dark colors

you should read her lore, again, read at least her bio. you say she is girly? She muderdered thousands of mans, indulging them in memories of sorrow and joy, she killed the man she love, she tortured herself in caves of Ionia returning years later able to survive without killing any more. so please, make sure you now what you are talkning about
