Romantic nightgown in wine color Plus size

I bought it online for Valentine's Day, but it doesn't fit; I am 180 cm tall, and the elastic is a few cm above, not below the chest. Below the chest 43 cm x 2, stretches to 72 cm x 2 /better not stretch it to the end, it will look nicer/. Length 113 cm. The fabric is in two layers, freely falling. Quality is superb. The color is darker than in the picture. Looks very feminine and romantic.
