Very cute and true to size but the top is Under Armor and very very tight. It looks like a water-repellent material. So, if your child is okay with clothes that fit snugly against their skin, then everything is fine. If not, then maybe go up a size to give a bit at the top. The pants are ankle-hugging, so if you go up a size, it shouldn't be too long if the pants hit the ankle. I'm a size 5 for a 4 year old and it fits perfectly. If it grows fast, it won't last long.
