This is a short-sleeved polo shirt from Polo Ralph Lauren. I bought it at the Ralph Lauren children's clothing store in Abeno Harukas. Size: 140 Color: Light blue It has a very stylish design, like it was painted with watercolors. It's also designed to hide stains, and I think it's a design that children will find easy to wear. There is a faint stain as shown in photo 5, but it's not very noticeable. It's a perfect design for energetic children.
