What is your belt size?
Take a belt you currently wear and measure from the tip of the buckle to the hole you use. That is your belt size.
Your belt size is NOT your pant size.
Your belt size is NOT your underwear size.
Your belt size is probably NOT what you wish your waist size is.
When you order a belt, I honestly do not care what hat size, pant size, or wife's brazier size you have. I will take the number you give me and make a belt for that size. If have you questions, contact me before having a belt made. If you order a 36 inch belt, you are going to get a belt that measures from the tip of the buckle to the center hole that is 36 inches. If you messed up and sent your pant size and you get a belt that doesn't fit your fat dumb ass, then you just made an expensive mistake.
Get the feeling I have had some idiots order belts who can't measure or have way over optimistic views of their waist size? You are absolutely correct.
I don't care if you are a fat ass, but don't be a dumb ass.
