Conus white double breasted cotton blazer size M on the tag, but it fits like an XS. This item is in good used condition although there are some minor imperfections such as small stains behind the lapel. No major visible flaws that can be seen while wearing. Please see the photos for flaws and measurements. I generally wear a size 2-4 and this is tight on me. I believe that this item is cotton, that's what it feels and looks like to me but since the care tag is in another language I am not positive. ⭐ Top rated seller 📭 Fast shipper 📦 Bundle discounts ❤️ Poshmark Ambassador level 2 double breasted blazer office cotton
