Pretty sure the style is his character. The pin is narrative driven, and the length and colour are a little touch to his slightly effeminate personality. Makes no sense to offer alternatives, it's not a dress up game.

I've never thought about it, but I would say probably not, unless it was part of an outfit in another scene or a different costume, otherwise that would mean redrawing parts of a lot of pictures for not really any benefit 🤔

I actually quite liked his look. A bit like a younger, better looking version of me.
