My son is a size 6/7. Carter's 6/7 t-shirts fit perfectly, but they're too expensive to buy in bulk just for t-shirts. I went with them as they are marked and they seem comfortable enough. They are a little big compared to other size 6/7 shirts but I think because they are also made for those who wear a size 8. I would give more stars if they sorted out the sizes and made 6/6x and 7/. 8 instead of mixing all these sizes together. I've washed them once in a hot white load and so far have had no shrinkage issues.
