I think they sent a size bigger for me. In size option they have 8-9 year like that but in size chart they didn't mention only 30 , 32 like that how anybody can make decide which size to buy? is size 30 for 7-8 year or 8-9 year? they gave measurement for size 30, 32. in selection they dont have that in selection you see just 7-8 year or 8-9 years.
