Women look(ed) equally beautiful in every decade.
Obviously the question should be, what decade had the best photography/lingerie/hairstyle...
I personally really like the early 80's Genesis magazine style. Even playboy had some amazing stuff back then. Some of the pictures taken then looked like art, really warm and inviting colors and sets, women teased alot more, and wore beautiful lingerie. Met Art doesnt hold a candle on that stuff.
If you like fakeness, early Scoreland is the best.
Id say if you were into videos though, the best videos were shot in the late 90's.
