Black double breast tie waist blazer

Super cute black blazer. Has a tie feature. No size or fabric tag. But I think it fits up to a medium. Material feels smooth and slinky. Has a slight stretch to it. Double breast feature. Approximate measurements: Shoulder to shoulder: 16.5” Pit to pit: 21” Pit to bottom hem: 18” Top to bottom hem: 28.5” Sleeve length: 21.5”
