This outfit is cute but I felt it ran small. My daughter is 19 months and I ordered size 3T for the holidays. Granted, she is a little bigger but even 3T was way too small. My daughter is almost 3 feet and 27 pounds. You would think a 3T would fit but it was too tight/short. I exchanged it for a 4T and hope it will work out. I plan to use it for Christmas. It is short sleeves but we live in NC and with all of the cooking in the house, she is warm inside. The coat is adorable, but does not provide much warmth. The hat is the cutest! I actually like that it is short sleeve because last year when she was one, she wore a long sleeve dress with white fluffy sleeves and it got all in her food. This dress is perfect with the short sleeves, she can make a huge mess and it washes and the sleeves are not there. I love it but I think it runs very small.
