Zip/Button... Zip-up Seasonality... Spring, Autumn, Winter The inside is fleece, so it's warm. It looks like it has some pilling in the photos, but... because it's a dark color, it's not that noticeable. I've taken good care of it! No stains or frays. It can be worn as loungewear, or over pajamas... When going out, you can wear it on its own, or under a jacket... How about it?
