Length: 79cm Width (underarm): 57cm Due to the drop shoulder design, the sleeve length is approximately 77cm. Shoulder width: 64cm, Sleeve length: 45cm (for reference) Material: 53% Rayon, 47% Acrylic Color: Black Size S, but it's a bit oversized. I wear another one of these regularly, so I think someone who usually wears a size M could wear this comfortably. If you're a size S, it might be a bit loose, so it might look cute paired with mini pants or a skirt. It may also depend on individual body types, so please use the actual measurements as a reference. It's a smooth, slightly thin knit, so it doesn't feel bulky and is easy to wear either as a layer or on its own. Price negotiation not accepted.
