Gucci hummingbird embroidered sweater

Absolutely gorgeous like new condition Gucci embroidered hummingbird sweater. Metallic sleeves and collar . Beautiful embroidered flowers and hummingbird. I'm unsure of the fabric but it is stretchy so I feel like it's elastane/ cotton blend? I received the sweater in a bag of clothing from woman in Vancouver ( so I cannot confirm authenticity) I don't see a size tag anywhere but this will fit an x small or small I found another sweater like this on first dibs for $1,411.
