Hello! Thank you for viewing my listing. This is a long-sleeved knit sweater from Zara! It's thin, so it can be worn neatly as an inner layer under a jacket. The orange and navy stripes are lovely. I've worn it 2-3 times, but it's clean with no noticeable stains or damage. I'm decluttering, so I'm selling it at a low price. The size is S, but it feels like it would fit up to a size M.
