I am currently reading "Female Chauvinist Pigs" by Ariel Levy, and let me just state this for the record that it is a fantastic book and everyone should read it!
Here are a couple of feminism inspired outfits featuring reds and blues.
Beloved "Battles" shirt (I got at Sasquatch last May). The skirt is thrifted and super awesome. Red cardigan reminds me a lot of what women wore during the 50's for some reason, before the second wave of feminism.
I bought the paisley shirt from a girl who was selling her clothes on campus in the AQ...quite strange how I went shopping at school. But it reminds me of the 60's, the height of the sexual revolution as well as the rise of feminism.
