It's size 15! Everything in the photos is included in the set! I bought it for my child's entrance ceremony at Aeon for 40,000 yen, but it turned out that everyone was dressed more casually than I expected, so I no longer need it... I tried on a suit for fitting at Aeon, so this is a new item with tags! I will consider discounts in the future, so please feel free to contact me⋆*
