I got 18-24 months for my stocky one year old. I had to hem the pants for his short legs but otherwise they fit perfectly. I used the excess fabric from the pants to sew a pocket on one side so he had a pocket watch (not pictured, he kept chewing on it) so keep in mind the vest doesn't actually have pockets but the pants do He was the most beautiful birthday boy! I mean only the cutest. We were very happy with the result of the costume!
