DESCRIPTION:
Late 60's to early 70's Coco's of California PERFECT condition 2 pc. The blue sash is not included as for it belongs to a robe I have but there seems to have once been some sash or belt long gone by now. This is in basically unworn or barely worn and well cared for condition. No stains, no damage seen. It is a busy print so small imperfections may have been missed but the over condition says I probably didn't miss a thing LOL
The duster or over dress is very sheer and light and the sundress under is in great condition.
