size 2T - 5T...a delightful vest for the wild child! fun to wear, with that extra blanket of warmth that can easily be put on and taken off. this one has been in my family since the late 70's, and still has plenty of life! there is a small area near a seam that has some loose ends, keep as is or stitch it up. measurements are in pics. this is a warm wool blend, has been washed several times, is durable and can take some rough play!
