Larger. 18 is comfortable. T shirts are thin. Half ** logo will be made on 2 shirts. I don't know why I can't post a photo. But I was a little upset and ordered 2 sets for my twins. There isn't another one yet. Update I received the 2nd set of shirts. Size 14 is the same as size 18. It's a bit frustrating that this applies to my twins who wear different sizes.
