I bought these shirts for my niece and the first time she couldn't wear the medium one so I ordered a large one and then I noticed it was too tight on my arms and also didn't cover my stomach. But in general, I just know that it's best to order her shirts from Amazon to find the right size, otherwise she just tries them on before I buy them.
