As you can see in the photos, there are signs of use. However, I believe it is fine to wear. I checked, but I couldn't find any stains. I wore it over a short-sleeved pajama top. I also had long-sleeved pajamas, but this was very useful for things like bathing, as I didn't have to roll up my sleeves. It also has a nursing pocket, so I think it's comfortable. (I use formula, so I can't comment on how it feels to use it.) It's loose and comfortable to wear. It also has pockets, which are convenient. Condition: Signs of use (please check the photos) No smokers No pets I washed it and stored it in a ziplock bag. Please refrain from purchasing if you are sensitive.
