This image illustration is from 1930. I've always been amused by this sort of flaunting imagery from the past.
Here's another press photo with pretty girls showing off the old and the new.
An finally this one, from 1945. The suit in the middle is from 1917 while the one on the left is prior to the 1900s. And that gorgeous two piece on the right is from 1945. I'd love to model a pin up shoot like this with suits ranging in time, wouldn't that be fun?
