I used to try to be real sneaky and hid my stuff the best i could but after enough shows I realized no one really looks at you that close.I really don't spend to much time hiding them in fact the mics you speak of I've used many times and Ill just clip them anywhere that works good, the coliar of my shirt ,or the sunglasses hanging around my neck. Don't spend to much time hiding the mics the only thing you have to worry about is the wires, when people see the wires is when they put 2 and 2 together otherwise Ive had security look right at them and they don't know the difference to most of them a microphone looks like a big ice cream cone just hide the wires. But if you don't feel comfortable I used to do this (in the winter anyway) go to the drug store and buy some vel curl (or how ever you spell that word) and buy some with adhesive back then just apply one side to the mics and wear a fleece sweatshirt with a collar and just stick them under the collar and your done. But again if you do it enough eventually your going to have them were the perform the best and not worry about the rest.
