My daughter is 4 1/2 but she is 5T and wears clothes and size S/M fits well and will be for a while. They're not baggy, but we don't have to strain to put them on. You look great. In those tights I sent her to gymnastics camp, where there was to be a superhero costume contest upon arrival, and then changed into normal clothes. When I picked her up at 6pm she was still wearing her tights, there were no snags or tears. My daughter is very rough so they are very well made. I would definitely buy again.
