Kachel silk dress from Anthropologie

Gorgeous navy blue sheath dress with white polka dots. Zipper in the back. 100% silk. Purchased from Anthropologie but never actually worn. Only potential flaw is a slightly darker bit running between two rows of polka dots, shown in the last photo (almost looks like a crease from folding). It’s not very noticeable (I didn’t spot it when I purchased the dress) but flagging as an FYI.
