Wearing a full superhero suit will be a bit too much. You will look crazy going around with say, a Superman suit. But if it is just a pair of cape socks? How does that sound? Great for superhero fans and those silly parties, it does look cool when worn with a matching superhero tee.
You can find socks of various superheroes, if you look for them. Batman, Robin and Wonder Woman are widely available apart from the one in the picture. Get one and feel like a superhero!
