A belt has a belt buckle and a belt strap. The belt can be part of a modular belt system that provides multiple straps and/or multiple buckles that can be assembled in different combinations. Preferably, the assembly of a custom belt can be accomplished in an in-store or point-of-sale environment. In some implementations, the strap can be coupled to the buckle without sewing or other processes that require expensive machinery and/or are time consuming. In some implementations, the strap is threaded to the buckle.
