Every child is unique so please use the sizing guide with caution. Some of our clothes are made to be a loose fit, some a tighter fit but as a general rule: our clothes are European sizing and cut generously.
They will fit up to the greater size of the dual sizing, e.g.. 4 yrs of the 4-5 yrs.
If you buy a 4T you would buy 4-5yrs.
Also remember that all of our woven pants have adjustable waists and our shirt sleeves roll up.
As a guide - please use the size chart measurements indicated in the images.
