My 3.5 year old has always been very close to 50% in height and weight. He wears 3T shorts for most brands and 4T shirts since most 3T shirts are short now. I ordered the 4T in green and it's perfect. It will last all summer but won't fit next year. The sleeve length seems great which others have complained about so not sure if that has been fixed? Bought 6/2018.
