First for my 18-24m girl I've ordered size 8M toddler based on the Ralph Lauren size chart. That says that they should be 14cm (5,5inches) long inside. However the inner boot turned out to be 17,5cm (6,9inches). Then I returned them and ordered the size 6. It turned out too be smaller 15,5cm (6,10 inches) while the size chart says that size 6 toddler should be 12cm (4,75inches). What a bulls*** the RL size chart?! Not Amazon, neither the Ivory goods and even Customer service of Ralph Lauren could not advise on inches corresponding to the size. I'm very disappointed.
