Eggplant purple vintage cocktail dress with beaded collar, sz 14

Gorgeous deep dark purple vintage sheath cocktail dress with beaded collar, fully lined. Beaded collar is purples and magentas. Size 14. Excellent vintage condition. I bought this beauty from a vintage store in Montreal and wore it to attend one wedding but it doesn't fit any more. No flaws that I can see, but I did have it altered slightly at the bust. So please do look closely at measurements.  measurements: pit to pit 19" across the front. length shoulder to hem 40.5". hip 22" across the front.
