I was DM ing on a local charter boat and we had a full boat, about 1/2 were tourists, I grabbed the hook for the float ball (Drift Diving) and realized at about 40 feet down that I was still wearing my sunglasses and wide brimmed hat! Fortunately my mask was around my neck. I stashed the glasses and wore the hat for the entire dive, when we got back on the boat one of the regulars asked if I meant to do that! I told him no but don't tell anyone else.
