Primary Kids Cozy Puffer Jacket

I purchased this in navy, size 14 for my 12.5 yr old son and it was too tight, even without a sweatshirt or sweater on. My kids have been wearing these coats over the years and I would say this size 14 runs very small so I was disappointed. I also think the color leans more purple than navy which is not what we would have wanted for a boy anyway. He has has the navy in the past and it was a true navy. So this had to go back.
