Abstract: A one-piece garment (e.g. infant/toddler Onesie or body suit) includes independent elastic bands threaded alongside the body of the garment, from the underarms down to the hip, that when pulled allow for custom fitting of the garment. Once pulled to the desired length, the bands are securable with a snap fastener post, located at the end of the strap, to snap fastener studs, located at varying points on the inside of the garment. The contraction of the elastic bands preferably creates a drawstring effect and provides a gathering force upon the garment, which is held securely in place with the snap fastener so that the one-piece garment thereby shortens in length around a wearer's torso creating a custom fit. The one-piece garment can be expanded as needed by releasing the snap fastener post and positioning it on a lower positioned snap fastener stud.
