Vintage maxi dress 70s

High-quality domestic maxi dress from the 70s, brand Kaisa Heikkilä Oy. The dress has long puff sleeves with elastic at the cuffs. Full-length zipper on the back. Fully lined with black lining fabric. Size label reads 40, but corresponds in modern sizing to about one size smaller, so I think it fits best a size 38. Armpit-to-armpit 47 cm, narrowest point of the empire waist 44 cm (x2), shoulder-to-hem 113 cm. Good condition.
