This jean jacket is a size large. It is perfect for fall. Look at the high-quality buttons. So cute. Do they even make clothes of this quality anymore? 100% cotton Small for its size like many Ralph Lauren piece. Personally I have larger upper arms, I wouldn’t recommend this protect if you share that feature with me :) This pre-owned item has been cleansed with Laundry Sanitizer and kept in a low moisture environment to help bring you a pre-loved item as close its original glory as possible. When you purchase pre-loved clothing, remember you are helping the environment and honoring the makers/workers/designers and wearers of those who loved these items previous. Respecting that our natural resources are limited and considering the pollution caused by disposable textiles makes a difference. Thank you 🫶🏻
