When I listen to that song sung by I&S, as I often still do, I think they are saying "leggings," not "goggles," and somehow wonder if the lady in question is initiating/inviting the idea of formal liason (matrimony?), starting off by suggesting that proper attire is the first step. Maybe I'm way off? I'm sure there are many versions of this song; I also know there are bluegrass instrumental versions of the tune.
