So - am way out of my depth here and I agree with the comment above - but I had imagined, given the fashion aspect you could consider something similar to the ear cuff design e.g: http://1.bp.blogspot.com/-PO5tT-NZ-zI/UYnN0LqO7_I/AAAAAAAABy... .. as worn in many asian countries. I imagine more of the design could be aesthetic, it could allow you to place the microphone closer to the ear canal (and potentially hide components behind the ear?)addressing some of the other comments about sound quality. - very happy to be wrong about all of the above :) - just some thoughts.
