Formal belts are usually narrower with a simple, sleek buckle and are typically made from smooth leather in dark colors like black or dark brown. Casual belts can be wider, made from more textured materials like suede or woven fabrics, and feature larger or more decorative buckles.

For a cohesive and polished look, match the color and material of your belt with your shoes. Black leather shoes should be worn with a black leather belt, and brown shoes with a brown belt. The finish and texture should also be similar.

Leather belts with pin buckle fastenings can be adjusted by punching additional holes. However, for a cleaner look and better durability, it’s recommended to purchase a belt that fits well from the start or use a belt with a sliding or ratchet buckle for easy adjustment.
