Mules, aren't shoes for your mom. They are in fact, shoes for you, to wear every single day of the week, all Spring and Summer long. Yes, you can go for a spiky stiletto mule - slightly uncomfortable, ultimately chic - a more reserved flat and otherwise homely mule, or opt for something youthful; the adorned (embellished to the hilt!) mule.
My personal fave, would include nothing short of casual slip-on type. "The Everyday Mule" for survival and utility; to be paired with boyfriend jeans and baggy tee's.
