Frock Girl has received many inquiries over the years if it's OK to wear tights w/ sandals & open-toed shoes. The answer is absolutely YES, if you follow the rules like Amal Clooney does! The chicest way to do it, is to wear a matching tight to the color of the leather of the shoe. This way it looks elegant and elongates the line of the leg all at the same time.
Mrs. Clooney sure has good taste in accessories . . . especially the one on her arm!
