Is it true that you are supposed to go up one size from your pant size to get your correct belt size? For example, I wear 32 inch waist pants so should I be buying 34 inch belts? I know this seems like an unusual question but I haven't been able to the the original source of this information and where else to ask than the Styleforum? I think it had something to do with having sufficient length at the tail so it would go past the first belt loop. Thanks.
