I'm writing this review because many of the previous reviews have said the shirts run small, but that wasn't my experience. My 5 year old is medium height and wears a size 5/6 so I bought a size 6 shirt. It fits well; It's definitely not tight and has room to grow and the head hole is fine. If there was a size 5 I would probably buy it instead of the b/c swim shirts which stretch slightly. I can't say anything about wearing it yet, but the shirt seems to be of good quality.
