I got a big (9-10T) in this UNACOO 2 Pack Crew Neck Solid Color Short Sleeve T-Shirts for Boys Girls. Although my 8.5 year old daughter's shirts fit the way we would like, there is still some room for growth. For reference, she is 51 inches tall (see attached photos). The shirts are really soft and breathable, made from 100% cotton. Pretty thin and light. Imagine being able to actually see through the shirt. Overall good looking shirts. They appear to be well tailored and of inferior quality.
