If I Were A Designer: Sport-work Clothes

A few years ago I started to imagine clothes able to be used at the office (a kind of serious-casual?) and for sport without changing yourself.
No one I talked about seen that it could be a possible project. I still believe in it. Even more since Quiksilver introduced this exact idea for real:

Should I restart my project?

(in fact, my idea is good but I don't have the resources to develop it... anyway, it's too late to offer it at Quiksilver)
