Purchased in Paris at Printemps department store May 2022. I made the mistake of washing in machine on delicate cycle (per instructions on tag) but it should have been hand washed or dry cleaning b/c it shrunk enough to be too tight across my bust. It was laundered 1x after several wears and I have not worn since. I would say it is more like a loose XS fit now, whereas before it was a loose S fit. It just does not work on me any longer. Extra buttons that came with top will be included.
