This is an Agnes B. check shirt. I believe the size is 4 years old, around 100-110cm. It's in beautiful condition as it was only worn once for a wedding. It's thin, so it can be used now or as a light jacket in the summer. My 5-year-old son, who is of average build, wore it. I hope this helps you. *Please understand that this is a personal inspection and item is stored at home.
