"I purchased this shoe online and was very disappointed that I couldn't wear it. It's very pretty and a lot more iridescent than pictured, but it was way too big. I wear a 7.5 shoe (the size I ordered) and can occasionally get away with an 8, but this shoe wouldn't stay on. I really wanted to keep it, but the back slipped off my heel with every step. I returned it in store, but wound up buying a different shoe."
