70's/80's Puple Full Sweep Nightgown Maxi Dress by Olga1970s or 1980s Olga nylon nightgown in purple. Olga intimates stand out as the premier brand for flattering style and stretchy comfy fit. Purple is a most rare color by this label. Overall good condition but does show minor signs of wear: a couple snags, and top of straps have been shortened a bit but can be easily ley out if desired. see photos.
