COMME CA ISM Denim Jacket Selling because it no longer fits. There is some wear on the cuffs and underarms, but there are no noticeable stains or tears, and I think it's relatively clean. The sleeves and underarm areas are made of a stretchy, lightweight material. It's not as heavy as a denim jacket, and it's light, stretchy, and soft, making it easy to wear. The design is also stylish and functional, and I found it very useful. I am looking forward to your purchase if you understand that this is a used item that a child has worn.
