This is a set of two T-shirts: one from the American brand Gymboree and the other featuring a Japanese flag design. They have a slightly oversized design, which looks good when worn. The age表記 (age indication) in the size column varies by manufacturer, but these two shirts are almost the same size when layered, and are closer to a standard 9-10 year old size than a 7 year old size. Please refer to the actual measurements. 1. Gymboree 【Size】7 years old Chest 43cm Length 53cm 2. Japanese Flag Design 【Size】9-10 years old Chest 44cm Length 58cm 【Material】 100% Cotton Worn for one season, but still in good condition and can still be worn.
