...shoes Sweet little shoes for a child or baby doll in a white leather. Made by La Parisette, Made in Canada, 3 M478 8788. This looks to me like a marked size 3, but I do not know if vintage baby shoe sizes are similar to modern ones (modern size 5 or 6?). In good vintage condition with some light staining on the outside. With a white rubber sole (some yellowing) and writing in blue pen, the number 15 or 75 The Foot length measured underneath the shoe is 5-1/8 inches (13 cm)
