Vintage 70s Mary Martin Rainbow California and similar items

70s Mary Martin for Rainbow California lightweight chiffon midi length off shoulder ruffle dress with purple, violet, turquoise, yellow, and gray floral print. No fabric content, but it appears to have a nylon lining. The dress measures approximately 39 inches shoulder to him and 21 inches armpit to armpit. 19 inches straight across the waist and 21 inches across the hip. there is a drawstring above the keyhole opening at the neck. It can be used to adjust the off shoulder fit, or you can wear it up on the shoulder if you choose. The drawstring tightens in the front, but I can?t quite seem to get it to go all the way around, but I haven?t played with it as much as maybe I could have. It looks like one of the tales has been pulled through a little further because the chiffon covering ends and shows the lacing underneath. But it still works! I prefer the look off shoulder, but it?s up to you. Based on the measurements, I estimate this to be approximately a modern size large but please double check measurements to ensure the proper fit for you. It is featured on my size medium dress form for scale.
