A thin belt over a sufficiently long and light sweater is a classic look. Look for delicate belts at vintage stores. Recent fashion accessory trends have shifted from the thick, wide-belt to layering with skinny belts. Skinny belts are inexpensive to purchase, can be worn year-round, accentuate a thin waist, and are easy to mix-and-match to an existing wardrobe. The addition of a skinny belt to an outfit can make a woman look thinner and more fashion-forward.
