Dress, size 150 (white x gray) This was purchased online two years ago for an elementary school music recital. I only tried it on once at home when I bought it, and then stored it in a formal wear closet. I bought it early, and by the time it was the right season, my daughter's tastes had changed, so she never wore it and outgrew it. Regarding the color... It may be difficult to tell from the photos, but it's not black, it's a dark gray. The thin ribbon at the collar is black. Dress length: 79cm. Unfortunately, there is no washing tag, so I apologize that I don't know the care instructions. I checked the purchase history... Material composition: Cotton blend (80% cotton). I purchased it from a shop called YuWan for 4500 yen at the time. It will be shipped via Yu-Packet Post. Thank you.
