Choose a belt with a little extra length
Whether you’re wearing a dress or casual belt, there should only be a bit of material left over after it’s fastened, around 2 in (5.1 cm) to 4 in (10 cm). You should be able to tuck the end of your belt into the first belt loop on your pants, or the loop on the belt itself.
Choose leather belts for formal occasions
You don’t have to get real leather, of course. But your dress belt should look like leather. It looks more formal and will also match your shoes.
Choose cloth belts for everyday wear
