Followed pattern for the 3-4 yr. old size. My granddaughter is 3, but wears a size 5. I crochet on the loose side, so I usually make a size smaller or go down in hook size. This turned out to fit her perfectly. I crocheted 21 rows on the body, 4 rows on the sleeves, and added one round of single crochet for the border. I am thinking of adding another round of sc around the neck.

Pattern is very well written, concise, and easy to follow. Color coded for size. Link to video tutorial for special stitch if needed. I would definitely recommend this pattern!
