This is a sleeveless, ribbed knit sweater vest made from wool or a wool-blend fabric. The fabric has a soft texture with a structured ribbed pattern, providing warmth and comfort. The vest is predominantly purple with contrasting green trim along the neckline and armholes, adding a stylish touch. This type of fabric is commonly used in winter clothing due to its insulating properties. The high-neck design suggests it is meant for layering in colder weather.
