This is a Uniqlo cut-and-sew top. The size is S. I bought it several years ago and it's new and unused. I don't think there are any noticeable stains, but there might be some overlooked spots or fading since it's white, so please refrain from purchasing if you are looking for a perfect item. I will fold it small and ship it via Yu-packet or Nekopos. Please leave a comment before purchasing.
