Designer silk Striped top

Elevate your style with this oversized beautiful top I’ve had it forever and worse it open as a jacket to a wedding. It has a slight eggplant color in some light but also looks black or a dark gray. The tags were cut out but it feels like silk. The cut makes me think it might be the very high end Escandar but I’m not sure. Natural slubs in the fabric make me think it’s silk.
