What I do is specifically not fashion. By that, I mean that what is "in style" is irrelevant when I am working with an individual client. Even people who think they have no fashion sense have very specific and unique tastes.
Is everyone a potential customer? No - nor should they be. A custom item is about a very specific item at a very specific point in your life. Not that we should assign it too much importance - clothing is semi-disposable after all, but it is a real experience, a process, a project... Having a garment or accessory custom made is a unique and specific experience better saved for your life's special moments.
I am passionate about personal expression through clothing. It really is a form of communication.
