I don't know about laughter, but there's certainly a sense of "all is not right with humanity" every time I see pictures of women back in the 80s and 90s wearing big ol' shoulder pads or poofy sleeves. Oy.
Speaking of old fashions, both my grandmom and great grandmother used to enter swimsuit contests back when they were teenagers. For my great grandmother, this would have been in the 1920s, and for my grandmother it was the 1940s. Back when I was a little kid I found their contest photos, and those photos were the first time it really dawned on me that progress and fashion and all that wasn't some steady march always in one direction. The swimsuits from the 1920s were as skimpy as anything you'd expect from the more modern times - teeny little bikinis that left little to the imagination (but still managed to cover the butt, because people still had some sense of decorum!). But the pictures of my grandmother in the 1940s were entirely different. Everyone was in one pieces, with strategically placed ruffles or other accents to add more modesty. It's so neat to me that little things like fashion can illustrate cultural shifts like that.
