Handmade 1970s Full Length Maxi Dress

I believe this was made by my grandma for my mom’s junior prom back in 1975. Perfect vintage cottagecore ethereal vibes in a sunny yellow, subtle striping and puffy sleeves with lace trim and a scoop neckline. Ribbon floral tie at the back, check out the pictures for measurements and sizing. Probably would fit an 8 or so. Decent quality for being 50 years old, but also look at the pictures for details, elastic in the sleeves is a bit loose.
