Gunslinger Hats and others in their alchemy path clip very noticeably at the neck on nearly all armors, and the tie on the back winks in and out of existence/visibility constantly. This becomes more and more noticeable the taller one becomes, as the head stays the same as the body (and thus armor neck pieces) becomes larger.
If I were to propose a solution, it would be to remove the bandana mask (which is the source of the problem) and make it an accessory instead!
