This design pattern is mainly based on the sleeveless and drop-shoulder long vest that emphasizes the waist. The neckline has an intimate small design with a short stand-up collar extending from the back to the clavicle, and highlights the three-dimensional lines of the shoulders and neck, but will not affect the aesthetics of the front of the neck. The built-in drawstring strap on the left can be used to freely adjust the shape of the garment.
