Hi all, this past fall I got the florence shirt in rosewood directly from a sezane store. I loved the cut so much, I wanted to get more of them but the colors I was interested in were unfortunately out of stock. So I got one on poshmark and the only difference in quality I noticed we the buttons were backed with plastic vs metal. I just received another color from poshmark yesterday (navy with white polka dots) and was disappointed with the fabric. The buttons were also backed with plastic, so I'm thinking that manufacturing may have changed a bit, but it didn't have the same shimmer/luster as the other two (or two of my other sezane silks) or the same weight. I'm questioning if it's a dupe, it feels just way too different. There is the tiniest if shimmers, but it's slippery which to me indicates it might not be silk. Before I report the seller as selling something inauthentic, does anybody know if the florence shirt silk has changed in quality (for the better) over the years? I'm having a difficult time trusting myself to judge between real silk and fake, but I do feel cheated.
