I've already looked at several sets of photos. I wasn't in highschool in 1969, but after looking at the "1969 highschool fashions" set, I find I still remember those clothes really well - the patterned skirts and those patterned tights, and the midriff-baring shirts with the hiphuggers.
One day I typed "Retro-something" into Google search. One of the sites had an innocent enough looking name - so I clicked it. Imagine my surprise when it was a site for . . . naughty pictures of yesteryear.
I don't think it had ever occurred to me, before, that shaving would be difficult, prior to the invention of safety razors.
