These are the cutest shirts- cotton, soft, thick- good quality but SMALL. Returned because of size and ordered a bigger size. I added a picture for reference- the other is a cotton 7-8 from Disney - I feel like the M /8 amazon was more a 6. I definitely recommend these shirts though just size up at least one size.
