Totally unique top bought in Paris, France

I bought this top which I loved in Paris, but it is too small for me. Beautiful fabric,round neck. The back has beautiful buttoned feature and it is longer than the front. It is very blousy. If I don’t pull it open armpit to armpit is 17inches. But it will extend outward to almost 23 inches. It’s made to hang loose in front with some gathering at the neck. from shoulder to body front is 21 inches and 22 1/2 inches in the back. Adorable and unique top. Sud•express. Pet and smoke-free home. Gently used.
