Vintage 60's Little Black Dress, size 8-10

This is a beautiful vintage cocktail dress that I estimate was made in the early 60's. There is no label or fabric content but it is fully lined and there is a size label in it. Size label says 14 but keep in mind vintage sizing is 2-3X bigger than modern sizing so please note the measurements. I estimate this is a modern 8-10 and someone with a smaller bust. In excellent vintage condition. Measurements laid flat: armpit to armpit-17.5", waist 14", shoulder seam to hem 40".
