Art Deco Beaded Blouson Dress with Halter Neckline

A seamstress has taken in the bottom for th dress to be the right length for me (5'4") with heels. There are marks at the bottom of the dress (see pic). I haven't tried any detergent of any sort, yet that layer is covered by the sequence layer and is only noticed if you are up close and looking for it. Size: 2. Color: Nude. The dress was worn once for a wedding - a beautiful wedding, I may add 😜
