The sleeves are made of a sheer material, making it easy to wear. Made of 100% polyester, it's comfortable and breathable. It's easy to match with both dressy and casual outfits. I've worn it a few times, but I no longer have the opportunity to wear it, so I'm offering it to someone who will. - Color: Navy (The actual color is closer to black than in the photos) - Size: F (Free Size) Thank you for looking.
