Really small. Looks like a baby sweater honestly. I have a petite 8 year old, 20th percentile height and weight and the size 8 is like a skin tight belly sweater on her. Size up. Otherwise it's really cute, love the buttons on it.
It took one month to get the coat after I placed the order. The coat is pretty. But the size seems like runs a little bit small. Luckily I bought size 4T for my 1.5 years baby. It fits well.
