Navy formal suit. This is a 3-piece set including a long-sleeved shirt, pants, and vest. Worn only once. There were no tags originally, but it's probably around size 100-110 (Japanese sizes). Please check the photos as I've included a measuring tape. The thread ends were originally a bit rough, but there are no stains and it's still in good condition. Although it's a formal suit, the material is similar to everyday wear, so please refrain from purchasing if you are looking for a more crisp, formal material. The mustache-patterned shirt is also cute, and it looked super cute on my child, lol. It's thin, so it seems like it could be worn in spring. I wanted to dress my child in it more, but they outgrew it after only one wear. How about it for weddings, parties, Shichi-Go-San (a traditional Japanese festival for children), or special occasions?
