Gorgeous boucle fabric, very Coco CH… can’t add the name of the designer, meta will not allow it… but you know who we mean by COCO. It reminds of their iconic style. They use this fabric in most of their collections. 
It is a mixed material in lilac in boucle and crepe fabric. Polka dot satin lining. 
Beautiful button detail. One and only. Handmade.
