Vintage Yves Saint Laurent YSL cobalt blue open back gown halter maxi dress 36

Gently used & has minor signs of wear - four TINY holes (not even noticeable in my opinion) near bottom of dress, as shown in photos #3 and #4 and then a little bit of dirt near bottom of dress. Photo #7 shows TINY hole near chest (that’s sorta by armpit) and snag. Vintage Yves Saint Laurent rive gauche - not sure what decade… perhaps 70s or 80s ?
