My son is 6 years old who wears a boys xs size 4/5 in clothing? does the costume run small? do i buy a small or medium? he's average height

We bought this for our now 10 year old who was 7 or 8 at the time. He's pretty thin and probably was in size 8 then so we got him a medium. The fabric is stretchy so it fit him then and he can still pretty much fit into it now.
