Our daughter's school uniform from Landsend, everything is pretty much in the ordering phase but we have the option to buy from any retailer but we went to the Landsend store and they measured our daughter by them and their sizes, she is 5, but from Notica. She is 6 years old, the quality of this shirt is as good or better than Landsend but at a significant savings :) Be careful when comparing sizes with Landsend
