Abstract: A system that includes a family of base bags that can accept customizable decorative and/or functional outer panels. Each outer panel may change the aesthetic and appearance of the base bag. The complete bag may comprise a base bag and one or more panels that are affixed to a portion of the outer surface of the base bag. The panels may have fastening elements that are positioned in the same locations, allowing the panel elements to be affixed to all of the different base bags individually. Each bag can be affixed with one or more panels depending on the style of bag. Each bag has fasteners that may mate with corresponding panel fasteners.
