FOREVER Navy Jacket Size S Shoulder width: 40cm Sleeve length: 61cm Body width: 40cm Length: 64cm A little small for someone 164cm tall and weighing 56kg. I usually wear a size L. It's a bit too snug when I wear it. It has shoulder pads and the shoulders are well-constructed, so it doesn't feel constricting. It has one button. There are two side pockets and one chest pocket. It can be used for elementary school graduation ceremonies. It can also be used for taller children. Why not consider it?
