I might be getting a Brooks Brothers rugby shirt in their coming BIG sale, starting Tuesday. I haven't had a rugby shirt for several years but recall it was always a hassle trying to come up with what should be worn under it. When I got my first one, also a BB, their salesman suggested a white shirt (assumably dress) would look snappy, but I don't even own a white dress shirt at the moment and am convinced it doesn't have to be that limiting. I know the classic rugby has a white collar so it would look good, but still.... Basically I think of a casual, knit polo shirt - short or long sleeve - as being fine with a t-shirt underneath like, say, a flannel shirt. But not sure about a rugby shirt over a t-shirt. Seems it might not look too swift wearing a typically horizontally striped rugby shirt over a plaid shirt. I realize the shirt underneath is barely seen, but subtle is, as often, the name of the game. I notice BB doesn't show guys wearing rugby shirts in their catalogs; maybe they're confused too?
