Modular Clothing

Make: Online’s recent Math Monday post features a fashion roundup on modular clothing.
George Hart for the Museum of Mathematics writes:

The mathematics of modular textiles allows you to take many small pieces of slotted fabric and interconnect them into a do-it-yourself garment. There is no sewing as the textile and the garment are created simultaneously. The parts can later be rearranged if perhaps you want to make a color accent, remove a stain, or just show a little more skin. Designers in the fashion world have taken this idea in various directions, using various underlying tessellations.
