COS Socks first appeared on Chictopia's streetstyle gallery in Winter 2009 seen on Paris blogger Adeline_R of adelinerapon.blogspot.com. She styled her blue COS socks with a gray The Kooples sweater, blue Levi's shorts, and blue Guerissol coat. Since then, COS Socks have grown in popularity as bloggers from London, Baku, and Hampshire have discovered them. COS Socks are generally seen in chic, preppy, and urban style. Popular types of COS Socks are checkered. Blogger's favorite colors are blue, gray, navy, and black.
