Gentleman
Your threads are humble and that makes you a perfect gentleman. You don't have to have fancy clothes to be a gentleman, just humble ones that don't stand out and show off too much. That shows how polite you are.
Picture yourself as the perfect gentleman. You may not have a fancy top hat and tie, but you're humble about what you wear and you're kind to everyone.

Unfortunately, as a gentleman who dresses humbly, you're always getting kicked in the shins (しん) by rude kids (and occasionally rude adults).
But you're a gentleman, so you don't kick their shins back, you smile and hold in the pain. No matter how bad your shins hurt, you never fight back!
