I wear suits a lot. I find that my Spyderco Military wears well on my dark suits with its dark clip so no one sees it. I have my whistle and Photon on the key chain so that is covered. I carry my Altoids FAK in the inside left breast pocket normally. If you keep a jacket on then belt stuff is even less of a problem. I don't carry a multi tool, but I don't know why that coudn't fit in the right hand breast pocket. My phone is in the right hand breast pocket. Wallet left front pants with keys. Usually I have a bunch of other stuff in my computer bag, but this is obviously not the case at a party. In those cases I really try to keep my wits about me and keep track of the nearest exits, things like that. Oh and I have always carried a bandana suit or no suit. They can fit anywhere.
