Vintage I.Magnin dress

Amazing vintage dress by I.Magnin from 60s or 70s zipper up the back hook and eye closure as well at waist. in great vintage condition. it is authentic vintage and has been around for many years so it is not expected to be perfect. I looked it over very closely and these are the things I found to note all very minor and none of these did I notice while trying on. a long thread or two at the neck possible slight dingy flower at the armpit ( see photo). hard to tell if it is there or not imo. right shoulder has a little pin prick and possible slight dinginess at neck ( see photo) purchased at a vintage shop and not worn by me ( I gained a few lbs before getting around to wearing it) measurements in photos ask any questions you have please
