The inner vest is removable. I think it can be used in 3 ways: vest only, coat only, or together. There is a spot stain on the back (see image 7). I don't think it's very noticeable, but please be aware of it. The sleeves are slightly fuzzy from being used by a child. There is a possibility of changing the shipping method from Rakuraku Mercari to Yu-Yu Mercari. If you have a preference, please let me know in advance.
