My daughter loves this jacket. No label for size but I think it is a large or extra large kids so a 16 or an 18. Unisex Can be worn on either side. Excellent quality and design!! So well made. Looks as if it is unworn yet my daughter has worn this a number of times. Can be machine washed. Good for a Brooklyn winter with a sweater underneath. Not good for a Canadian winter. It is lightweight! Good for a cold fall day too. I love this jacket and you will too!!! Arm from shoulder 22 inches Bottom flat across without pulling elastic is 16 inches across Length from shoulder is 22 inches
