Well, this past summer I was down in Pennsylvania as CIT at a kids summer camp. I was working with kids from age 8-15 (the younger and the older ends of the spectrum I spent the most time with). I found with the littler-uns, if they even batted an eye, it would only take one good clear answer as to why I wore it and they were happy for the whole summer (they never asked about what was under). Delaing with the older ones (13-15) was a little more fun, the girls didn't need any reason, only a few of them weren't fans, and the guys, well, once they saw how the girls formed an opinion of it, their questions quickly turned towards inquiring about it's impressive effect on the ladies. Oh, and my usual answer to the older guys about what was under was usually "well, when you get one, then you won't have to ask me" (the girls I simply refused to answer, as it could be taken out of context as an inappropriate discussion according to my position).
