I looked on the wiki and noticed that all Armor Rear accessories are tails. I got an idea for an accesory. It's called a Sheriff Belt, and by Sheriff Belt; you should already be able to tell that it shares an appearance with this.

This belt comes in cool, divine, dusky, fancy, heavy, military, prismatic, regal, toasty and divine. There's no volcanic belt.

Cool - Navy blue belt with a blue buckle.
Divine - Beige belt with a silver buckle.
Dusky - Gray belt with a swampy green buckle.
Fancy - Purple belt with a black buckle.
Heavy - Gray belt with red buckle.
Military - Green belt with dark beige buckle.
Prismatic - Your personal color with a silver buckle.
Regal - Yellow belt with green buckle.
Toasty - Red belt with brown buckle.

This belt could match with gunslinger sets, which is another reason why I thought to suggest this.
