Black ribbed lace detail, fitted long sleeve top from Zara. The buttons are actually decorative not as shown unbuttoned on the modal. About 13 1/2 inches across the bust but does have stretch. About 20 inches top back to bottom I cut the care tag out because it was scratching my side. Its 95% cotton and 5% spandex. INCLUDING A MATCHING TANK BUT IN SIZE MEDIUM I do have the cream off white color too if interested.
