I recently invested in some white, tan and grey EMW, B6 and Cos-11 lav’s. which have saved me alot in the past season of my Reality tv show. A number of the cast members wear very thin tank tops and retro style T-Shirts which show the standard black microphone wire, However the white lav wire is easier to hide and makes my job much easier. So in the future consider adding some colored lav microphones to your kit. It may help you too.
