Some might use the term ‘multi-functional’, others prefer ‘convertible’ or 'adaptable’. The semantics may vary but, conceptually speaking, modular fashion translates into a garment, shoe or accessory that changes shape or form for different purposes.
A modular garment is one that can be disassembled into different parts, or modules, and reassembled at the wearer’s will. This is generally achieved through a variety of fastenings, from buttons and zips to press studs and Velcro.
These fasteners are used to attach or detach optional extras such as collars, hoods and pockets to transform one kind of a garment to another, such as a pair of trousers which can become shorts thanks to detachable leg bottoms.
