I bought am XSmall for my 40 inch 39lb tot and its too big but wearable for the next couple of years. She'll grow into it . It's definitely runs in non youth sizes . The quality is super nice. No fading but I haven't washed it yet. Over all I do like the shirt great for Shark weekKid loves bugs! Shrunk a little bit, not too much & didn't wrinkle badly.This seemed a little small compared to other brands, but it said preshrunk on the label. Hoping that’s true.Great tshirt, always wash and dry inside out so you don't wear out the image.Item as described. Quick shipping. Would buy again.Sharks are not centered, off center and in the on side - weirdGrandson ten loves it and it glows in the dark.The name says Kidteee but the sizes are more like adults not youth. The color was not orange but off color - more coral. The art work looked great but nothing else was right. Very disappointed.
