This is a Theory cotton-cashmere knit. It's a size S, but it's a loose-fitting knit. I think it can be worn casually. The neckline, sleeve cuffs, and hem have a fluttering design, giving it a slightly vintage and cute look. Here are the approximate measurements: Length: 54cm Width: 50cm Sleeve length: 60cm It's a slightly ashy pale pink and is very cute. It's a beautiful item worn about four times, but please understand that it is a used item before purchasing.
