Vintage 60's-70's Long Dress

Vintage 60's-70's in patterned cream and embroidered in green long dress. I've taken a lot of pictures so as to get a good idea for meticulous tailoring of this dress. I believe to be cotton with a gauze lining 3/4 way down dress. Crystal buttons adorn the front with princess neckline and seaming throughout the dress. There is no zip so the dress has to be pulled over the head to get it on. The only tag this dress has is for dry clean only. Bust 35 1/2" Waist 30 1/2" Sweep 46"
