Birdy Grey Grace convertible dress with slit in dark mauve 2X

Beautiful bridesmaid/formal dress by birdy grey. Color is a dusty mauve. Dress has two sashes in the front that can be worn in multiple ways. One sash has a string pulled in it but not noticeable when wearing. There is also a small stain on the bottom chiffon. I just took it to be dry cleaned so it may need to be spot cleaned. Size chart in photos. Flat measurements are pit to pit 20”, waist 19”, length 47”, and slit 26”
