I bought several brands but these are my favorites at least for my child. My daughter is very tall and thin for her age. She's almost 6 years old and has been weighing 40-42 pounds all year - she's just getting taller, not wider. They fit her perfectly but she is very slim. I would say the size is more than one size for a normal weight child than more for a child that age. I won't pay full price when there are so many brands to choose from.
