I also read a lot of reviews and was concerned about what size to order for my petite 2.5 year old girl. I have absolutely no dance experience so wasn't sure if leotards would naturally run small etc. I chose 2-4T for the leotard. I also ordered a small Capezio Tactel zip skirt. The swimsuit fit well. The skirt went up but looser. I'm worried the skirt will fall off while she's in class so I'm returning it for a size smaller. For the record, my daughter is just under 34 inches tall and weighs about 24 pounds with a chest of about 19.5 inches. My point is that if you know your child is petite, I would be wary of the sizing. At first I was surprised how small the swimsuit looked when I took it out of the box, but it stretches a lot. I will say that I don't think the size 2-4T would fit an average height four year old.
