Although Lapel microphones provide freedom of movement, a Head microphone is really the best choice. Many are available in beige or black and are extremely small and light weight. A good Head microphone can provide very natural, high quality sound. The volume and tone never change because the microphone is always in the same position relative to your mouth. You can get plenty of Gain before Feedback because it is close to your mouth and it is so small and inconspicuous that you and everyone else will probably forget it is even there.
