This is a lovely thick, warm coat with a lined, foldaway hood - good quality.
My daughter is eight years old and usually wears clothes that are age 9-10 years as she is quite tall (137cm). This size 7-8 years is slightly large in the body but hardly noticeable and will be fine with a thick jumper underneath. It is a perfect length in the body and sleeves.
I'm really happy with it, especially as it was such a good price.
