I feel like 80% of the hairstyles are unusable in most gear, a lot of hairstyles really don't consider clipping. I'd much prefer longer hair but everything just clips and looks really bad.
I think the solution would be to first make sure hairstyles are way more compatible with gear or even have options to take certain parts off a gear glam, I'd appreciate allowing hairstyles be tied to glams but I don't think it would fix the actual issue of how hairstyles are implemented.
