This is an oversized knit vest. With a knit that isn't too casual, I think it's a great adult vest that can be worn elegantly over a shirt! Made of cotton, it can be used in the spring and autumn. Color: Black Neck: V-neck Material: 50% cotton, 50% acrylic Length: Approximately 71cm Width: Approximately 55cm (measured flat) It has only been worn 1-2 times and is in good condition, but please note that it has been stored at home.
