Used a few times. There are no noticeable stains. The size is listed as 9 months, but it seems to be around 70cm. Based on how it was worn, it seems slimmer than other brands. My older son, who is well-built, was bursting out of it when he tried to wear it at around 70cm (^_^;) (It was the perfect size for my slimmer second son).
