Today’s article is dedicated to flat mules and awesome ways how to make them work for you this Summer. It feels like we have a comeback of old trend and flat mules are among them. This nostalgic footwear design is so must-have. Last year we saw a major comeback of this style in fabulous high-heeled designs. This year we see flat mules that look like slippers to me. The flat version of mules looks really cute and weird. The backless design is really interesting, but it does look casual. I decided to bring you all my favorite looks with what to wear flat mules in real life.
