A small SAK and a Micra or Squirt should fit into a pocket of the dress suit. A metal case for cigarettes or cigarillos could provide room for some items of your regular kit and provides a pretext for carrying the lighter. A Photon or small Maglite could be attached to the key chain. I´m aware of the fact that this is much less than desireable but it´s better than nothing at all. If you´re lucky you could even extend the kit to your wife´s purse.
You could put a picture of your stuff into wallet to ease the signs of deprivation <img src="images/graemlins/wink.gif" alt="" />.
