Micing a bride for a wedding ceremony!?! (And I thought I had heard it all.)
Whatever you do, make sure all the wires, and mic, and transmitters are absolutely out of sight - I can hear the mother-of-the-bride already...
You may want to check with the bride about any tape, even medical tape - if the adhesive does in fact irritate her skin, it will be bad for later photographs that day. (I can hear the Mother-of-the-bride....)
But as legitimate suggestion (and I don't know anything about
microphone systems), is it feasible to use just one
microphone on the groom that will pick them both up? - he has pockets and no one really cares about him anyway. (Although it might depend on the faith and ceremony, I think most of their speaking is when side-by-side and while facing each other).
