No holes or stains but I'm not sure how the term 'pitting' applies to clothes, can you describe more what you mean by that?
There is a tiny green thread near an armpit that appears to have been twisted into the white yarn and the only reason it's worth mentioning is b/c, at first it looked like a tiny green spot but it's just part of the manufacturing process. It doesn't have any threads that are pulling out but it has what I'm going to call 'sweater fur'? The shell is 37% wool, 32% acrylic & 31% cotton so it has some 'fur' quality to it. I don't want to quite call it pilling but some people might. To me, it seems more like of a characteristic of the material, rather than annoying little fuzz balls, the fuzz is less ball like but has formed together in places, if you know what i mean. I can try to get a better pic of it. In case your wondering, it is machine washable in gentle cycle. I also noticed after going over it in that detail, that I HAVE THE WRONG SIZE! So thank you very much for your question. I can try to change that and hope it still works for people watching and bidding. My apologies, the tag says 18-24 MONTHS.
