The tag says 100, but it's clearly larger than that. I've listed it as 120 because it was perfect when she was wearing size 120 clothes. We used it when she was wearing clothes sized 110-120. My daughter is a bit slender, so she could still wear it even when she was wearing size 130 (the sleeves would be a bit short). The zipper was a little stiff to begin with, but it moves smoothly. I don't see any stains or dirt, but I apologize if I missed anything. Thank you for your understanding regarding used items.
