As a teenager I spotted a full spectrum of rainbow hair color and it was definitely a tell about my internal turmoil. When I see it and other strong subculture markers on adults it just makes me think they’re making things harder for themselves.
I just can’t take what looks like an angry teenager seriously as a professional. Same thing with tattoos, piercings, odd clothes, or over the top makeup.
You know how a lot of the hunter ring “dress code” is unwritten, but understood? It’s the same thing putting on your professional adult costume. It shows me that you’re willing to do/wear something that isn’t your favorite because you understand the benefits.
If you show up at the ring with green hair peaking out from under your helmet, it makes me think you either don’t understand opportunity cost, or that you don’t care. Wouldn’t effect your score if I were judging, but I wouldn’t want you catching the ride on my horse. Does that make sense?
If you’re still in high school, have at it!!! This is your time to get into whatever fashion silliness you want. Live it up! But if you’re going to present yourself as a professional (working student IS a pro) then make your life easier and tone it down. Show people you understand the rules and you’re willing to play by them.
