Vintage 60’s dress

Vintage handmade dress made in the 60”s by my grandmother she was a seamstress, not sure what the fabric is but I think cotton based on feel and weight, in great pre-owned condition, no holes or rips, done by hand so occasional threads on the the inside, 8 buttons down front and loops for belt, waist is 13inches across front, bust 17”, I’m 5”7 and modeling it’s to tight for me in the bust would fit a smaller back I’m usually a 34c, amazing print, awesome 60’s dress just to small for me sadly
