College fashion design class: are you into the fashionable looks more than the function? Why try to re-invent cycling shorts when they are already in existence?
For a pure fashion play, just spend the dollars on print. Leave the construction alone. Major manufacturers don't have much choice on print. I think they already did their marketing studies and know that the multi color styles are way too expensive to produce and way too risky for consumer acceptance.
For a real neat web site on form and fashion try Assos, a Swiss company.
