Maeve Anthropologie silk dress, size 2

Beautiful sleeveless ruffle dress that ties in the back. It’s a warm brown, 100% silk. Unlined, this is perfect for a baby or bridal shower or just a breezy day! Empire waist, side zip. Sadly, it looks like something got on this dress and there’s some residue. (Perhaps gum?) Please see the photos. I really think it could clean up nicely with a little cleaner! The largest spot is on the tie ribbon but it could totally be tied to hide the spot! Offers welcome 🛒
