Roberta of California vintage 1970s prairie/boho/western/bridal dress

Absolutely stunning and very rare 1970s Roberta of California white maxi dress. Some slight pulling at seams but no holes and no yellowing at armpits or neck etc, all buttons are present and the zipper works smoothly. Fabric tags have faded away but my guess is this is cotton gauze. Slightly sheer as you can see in the image and video. No size tag but I am 5’7” and an xs-s. I am wearing 3” heels with this dress and it still grazes the floor. I would say this is better for someone who is a true XXS to XS. Gunne Sax vibes! Pit to pit: 17.5” Shoulder to shoulder: 15” Waist: 13.25” Shoulder to hem: 60”
