I did not communicate with the store. On the child of 1,5 (height 83,5 cm, 12 kg) took 3 T with a margin. In the photo, the sleeves are rolled. The elastic band is tightened from below, a comfortable and bright raincoat-jacket.
Very beautiful jacket and fits good. I brought a 5T for a 4yr old that weighs 31lbs so it fits true to size. The child will have room to grow. Arrived to USA very quick, Thank you
