This is a formal wear set for boys/children. It's a 5-piece set including a jacket, pants, dress shirt, tie, and accessories. The size is "170". I received this set, which was purchased new on Amazon and only used once for a child's graduation ceremony. However, it's being sold because it no longer fits due to the child's growth spurt! The dress shirt has been washed but not ironed, so it's wrinkled. Please iron it before wearing. Photos 1-4 are from Amazon. <Reference> [mitsuhada] Elementary School Graduation Ceremony [Latest Series] Children's Formal Boys' Suit "Jacket, Pants, Dress Shirt, Tie, Accessories" Graduation Ceremony, Entrance Ceremony, Wedding, Presentation, Birthday Amazon Site https://www.amazon.co.jp/dp/B0CSZ1NBFL
