Ken, you've got what you need--two barrels one beside the other. Victorian shooting rags optional. The overall look is somewhere between Dickies workwear and prep--few buffalo skinners and mad Scots thrown in--so no one will even notice boat shoes and a tank top. Contact http://www.vintagers.org for copy of pre-registration form so you can get a handle on what you want to do, see, shoot. Raingear always a good choice.
