"Purchased these red shoes for my granddaugher, who was the Flower Girl in my daughter's wedding on May 26th. According to the measurements, should have worn a small. Purch'd a med. too, "just in case." The small was too small; the med. was a little large, but had the shoemaker sew a little white elastic band across the instep (like ballet shoes), which was invisible against her white frilly socks. They were a hit! And comfortable all day!"
