It's light and not too casual, making it suitable to wear to work. The fabric is somewhat sheer, but it comes with a lining, so it's reassuring. I wore it during the summer while pregnant. It can also be worn in spring and autumn. I don't recommend it for winter because it clings due to static electricity. I have other maternity wear items for sale, so please consider requesting a combined purchase! - Size: L - Waist Size: 69-77 - Material: 62% Polyester, 33% Rayon, 5% Polyurethane Thank you for looking.
