Do not shy away from the grosgrain belt. This timeless piece was made to be seen. Women, pair them with dresses. If opting for skirts or pants, tuck the front or entirety of your shirt into your bottom so the grosgrain is exposed. Men, a shirt flap tucked into your pants or shorts signals that you pay a little attention to how you look without trying too hard.
P.S. Currently I am employing grosgrain belts to update my trench.
