Purchased this suit for my 13 year old daughter.  She is 5' 1" and 78 pounds.  Fits just snug enough but will give her room to grow.  She immediately liked the suit and how it affects her body position in the water.  She is a 1:45 per 100 swimmer without a suit and she saves 10 seconds per 100 with the suit on.  Good flexibility in the shoulders. Good price versus renting a suit three times a year.
