Purchased at a TOMORROWLAND store. This is a very useful item, but I am selling it because I have too many vests. There is a stain next to the button. Please understand this before purchasing. Shop: TOMORROWLAND Brand: Ballsey Quoted from the official website: This high-gauge amunzen series is knitted on a computer jacquard machine using triacetate yarn and highly shrinkable polyester twisted yarn. It features a soft and smooth touch and an elegant luster. The vest has a mannish impression with its straight silhouette and double-breasted design, while the deep V-neckline that reaches below the bust creates a feminine balance. The exquisite length is also a key point, making it easy to match with pants, as well as dresses and skirts. It is a versatile plus-one item that can be widely used both on and off, depending on the styling. Product number: 11-07-22-07133
