My daughter turned 5 at the end of June. At last check, she was about 42 inches tall and weighed about 41 pounds. I bought her a size 6 based on the reviews and it fits perfectly. She has short legs so they technically reach her ankles, but they don't bunch up too much to look unkempt. They also appear to be of excellent quality, but time will tell!
