Vintage Banana Republic Pleated Formal Dress (1998), Pewter 14

I bought this dress decades ago because I loved it. I kept it because I loved it, but I’ve never actually worn it. It is beautiful, a raw silk type material. It’s been stored and will likely need to be steamed upon arrival to address folds from shipping. It could be great for prom, formals, etc. It has a side zipper. I don’t see care instructions but I’m guessing it’s dry clean only.
