Sezane Cassi Skirt Sz 42

I am not original owner but did buy it nwt. I washed it on gentle in a mesh laundry bag and laid flat to dry but never wore it (planned on wearing it over a bathing suit on a cruise to lunch, but ultimately didnt take it in the trip). the color was noir but looks mostly blue to me, with the dark blue background with pink and white daisy looking ditzy floral pattern, one ruffle on the front, side zip, fully lined, and embroidered front waist band in tan and pink. size 42 = us 10.
