Every man has at least one chino pants right??
Ever tried to put a regular(western) belt in your chino??
Yep, I know, that ain't working...
So you have two choices
1: buy a confection belt for costumes and hold your sweater down!!
2: go to your local leatherworker and have one kustom made!!
vegetable tanned leather.
old style original riveted.
praying hands because we're all sinners...
