Beautiful vintage 1960s/1970s Fairweather floral maxi dress

This dress is so beautiful. I’m not sure what exact vintage it is, but based on fabric/zipper I would say 60s/70s it is in excellent vintage condition. Only flaw I could find was where metal hook closure is at the top of the zipper the lining is a bit torn. An easy fix and does not affect look of dress at all. Fully lined. Fabric flower with beaded centre at the front. Halter style. Low back. This dress has no size listed, but put to pit measurements are 15” and waist 12”. There is no stretch to the waist. This would be for a size 0-2 or XXS to XS. Sadly too small for me, because I love it. Bright orange, pink, and purple floral sheer overlay.
