green label relaxing Cut and Sew Blouse Short Sleeves, Frill Sleeves Off-White 95% Polyester 5% Polyurethane It has a slight sheen and is almost completely opaque. The fabric is smooth and silky, doesn't cling to the body, and is also stretchy, making it extremely comfortable to wear. I tried it on after purchase and washed it, so the tag is not attached. Can be worn tucked in or out. It can be worn alone or under a jacket, making it versatile. The frill sleeves don't add bulk, so it can be worn under a jacket! It has a slightly elegant sheen, so it can also be used for formal occasions. Thank you.
