I will soon be attending a formal event that requires me to wear my suit. My suit has dress suspenders and the belt loops on the pants are too small for a holster-worthy belt. A shoulder holster wont work because I will want to be able to remove the jacket if it gets warm. I am looking for one of those "undershirt" holsters that is basically a white undershirt with a holster sewn or velocroed on it beneath the arm pit. Any suggestions on specific brands or types would be greatly appreciated, thanks.
