The swimsuit is from Birthday, and I think the rash guard was purchased at Nishimatsuya. The swimsuit is size 110, and the rash guard is size 100. I bought the swimsuit one size larger to make it easier to put on and take off. I chose a just-right size for the rash guard so it would be easy to move in, and they were worn together. There is a small stain on the right chest area of the rash guard. They were worn during water play, and also used at the beach, so sand has gotten into the fine weave of the fabric. (Images 5, 6, and 8 are the easiest to see this in) Therefore, I have priced them affordably. The sand couldn't be completely removed even after repeated washing, but the child didn't mind wearing them, so they were worn as is. I'm hoping to find someone who doesn't mind, such as someone who will also use them at the beach, or only for a short period during the summer!
