This is an outerwear item for boys from HUGO BOSS. It's very clean and stylish. The size is indicated as 10-138. It's a guide for around 10 years old, with a height of 138cm, but my child wore it perfectly at 9 years old, being slim. Please consider the size with a little room to spare. Purchased a year ago at a select shop in Takashimaya. Worn only once or twice and stored at home. The left underarm can be opened and closed with a zipper.
