Vintage 60s 70s floral maxi dress

Vintage black and white maxi dress. See pics for measurements, extra room in the chest. No tag (maybe handmade?), but would say it's between XL and 1X based on measurements. Full skirt. Snap closure on the sleeves. Some minor wear at the bottom hem and wrists but not very noticeable with the pattern. Overall in good condition especially for vintage!
