I bought this two years ago! I used it alternately with another swimsuit, so I've only worn it about 10 times! I don't see any yellowing or mold! I had a name sticker on the size tag, so there's some sticker residue. Please be aware of this before purchasing. Overall, it's in good condition, but there are a few places where threads are sticking out, which is common with children's clothing, even new ones. It's not something that happened from wearing it. My child has outgrown it, so I want to pass it on to someone who can use it! Thank you! I bought it because it looked cute, and I remember buying it at a store, but I've forgotten which one. I'm also selling other swimsuits in size 90, so I'll give you a 200 yen discount if you buy them together!
