Worn a few times. It gives the impression that there is some fading. It's made quite tight, and it fit well when my other clothes were size 90cm. I think it might be a little tight for a 3-year-old with a normal build. Therefore, I've listed the size as 90. I don't see any noticeable stains, but this is based on my own assessment. Thank you for your understanding. I will fold it up small for shipping.
