For the past couple of months, I have been drawn toward the typical 1940s thin, rounded brows. This has come to quite a shock to me. After always being a fan (and wearer) of a bolder, 'pin up' brow. I started to search out and study gorgeous women from the 1930s and 40s, out of curiosity. As seen in the pictures below, many stars sported this shape and style. That was a slightly more 'natural' brow, than compared to ones worn by stars such as Jean Harlow and Marlene Dietrich (above) earlier in the 1920s.
