I love socks. Striped, yellow, transparent, fluffy: you name it. They can make an outfit complete. However, socks are a nice way to communicate.
With socks you can play. For example when you are waring long trousers, you can show your socks to some people you want to communicate with. Seeing a potential date entering a cafe? Woke up on the wrong side of the bed? Say it with your socks.
