I bought XS (5/6) for my 5 year old and S (7/8) for my 7 year old based on the sizing suggestion . They seemed to match the length of the collar and arms, but were quite long on the torso. The top fits my daughter who normally fits in at 4t and is very petite for her age. She is about 33 pounds and 38 inches tall for comparison. But as said, below the waist the dress looks like a dress. Hopefully it gets a little smaller or at least gets a little more use. I'm sure we can accept it or at least fill it up for now. My son now roughly fits an 8 year old boy but can still wear some size 7 shirts. He's about 60 pounds and 4 feet tall, if that helps. The material is excellent and the colors are as shown. I have to embroider a logo on every shirt and this material shouldn't be a problem for that. Overall I am happy with the purchase and received about 10 different colors per child. All the colors looked great. I would purchase by your child's current shirt size to ensure an accurate fit. I think a smaller size would be nice but we're happy with what we have.
