These are great shirts for girls and I am actually making a ton of these for a birthday party! They've taken HTV well and the Next Level brand is always so soft so I know they will love them. I wish they gave you the number equivalents vs the measurements but it goes S 6/6X, M 7/8, L 10/12, XL 14/16 and I always size up if the customer tells me their daughter is a combo of sizes (12/14 for example).
