Who says that zippers always need to be practical? Form doesn't always have to follow function, or at least that's what designers are trying to tell us. Instead of following strict utilitarian rules, zippers are being used to decorate garments. They are slicing through looks in Paris much in the same way neon did in New York. Lining hems, trims, and edges, you will also see them used at Balenciaga and Jean Paul Gaultier to create geometrical shapes, while Jay Ahr stuck to something a little more free form.
