I could never really afford LaCoste; in the early 80s, they were $25 a pop, well beyond what my budget would allow at the time. I did have a rainbow of colors from Brittania, however.
At one point I did manage to buy the real deal. It was red, and I never wore it much because I got a size too small and was too naive to realize I could take it back and exchange it—even after I'd washed it.

In much later years I have been able to snag a few gently used alligators from eBay. Terribly out of fashion these days, but I still love them. Put one on, dab some Halston Z-14 behind my ears and I'm 25 years old with a 31-inch waist again.
Really, all Pastels? I remember these at that time, but never bought one for myself. They were seen being worn, more often than not, at The Twin Peaks Bar in San Francisco. I think this was around the time that the term, 'Yuppie' was being used. Black would have looked good I think.
B.T.W, you look very happy in the photo. Being 25 has its merits!
