Wow, leave it to the LIFE photo archives to completely swallow one of my afternoons. This time I managed to find various photos of American Cowgirls of the 1940s. In an era where pants were uncommon on most American women, every one of the ladies below is proudly styling an awesome pair of jeans or pants with really cool boots. These ladies are very cool. Enjoy the photos below, which all came from the LIFE archives.
