Bridesmade or formal dress

Birdy Grey Grace Convertible Dress with slit. Dark Mauve. Chiffon. Size M. More info at https://www.birdygrey.com/products/grace-convertible-dress-dark-mauve Worn for one event. Has some signs of wear at the bottom but otherwise in good condition. Runs small in my opinion. I am usually a size S. See size chart in photo
