Balenciaga crepe stylish fitted top like new size 40

Very cool top from Balenciaga I bought it a long time, it was worn once and dry-cleaned and sadly it never fitted again.Size is 40 French i think it translates to size US6 but if you are interested i will send the measurements to make sure it fits. It is made of viscose acetate mix, it is matte black with a satin detail in the front. beautifully constructed, fitted with zipper on a side, with square neckline.
