Size 38 which I think is equivalent to a US size 6 or 8 but I am not sure so please refer to Sezane’s website and size chart. Buttons up the back. The button has fringe from the lace some of the pieces hang down a little further than others. Please note that I wear perfume and own a dog. I will lint roll the item before shipping but there can be rouge dog hairs and it may have a perfume scent.
