Vintage Joseph Magnin colorful patchy maxi dress

Vintage Joseph Magnin colorful patchy maxi dress. Reminds me of highlighter colors minus the purple. Rare piece! Thin material, definitely sheer and textured at the bodice. Sleeveless. No marked size tag but I'd suggest for a small in women's but please refer to measurements to make sure it fits! Flaw: does have a tiny thread line rip near the back zipper and some other tiny rips on the inner lining. Tiny stitch repair near zipper and I do suggest replacing the zipper as it feels fragile but it's completely functional. Definitely a more delicate piece especially due to age. Measures 18 inches pit to pit (36 inches), waist is 14 inches (28 inches), hips are 19 inches (38 inches) and it is 53.5 inches long. Used item, has been washed.
