This is Korean children's clothing. The tailoring isn't perfect, but the design is cute! The long-sleeved T-shirt doesn't have a vest in the back! How about it for a small gathering, accompanying a child to an entrance ceremony, a birthday party, or Shichi-Go-San (a traditional Japanese festival for children)? I haven't worn it much, but there's a little bit of fuzzing and pilling. It seems like it can be removed with a pill remover. Please comment if you have any questions.
