Costume Navy and Gold sequined 1920’s flapper dress

Costume brand - not vintage, yes retro! - listed as size small but more like a large, it’s big! Purchased originally from Amazon, worn once for a costume party! FAKE FUR SHRUG NOT INCLUDED but is also available if you want to bundle! Pictures attempt to show that there is a zipper up one side but that it’s sewn together at the top of the zippered section - it came like that. It seemed unusual to me so I tried to get pictures that demonstrate that Open to offers :)
