Sparkly Vintage Dresses

I spotted these three decadent vintage dresses on Etsy and had to share. The Grecian halter neck dress is from Maefair Vintage ($108) and would be perfect for special occasions. The peach and silver dress is impossibly pretty and only $78 from Melsvanity. Finally, I had to flaunt the black cocktail dress with its incredible neckline from Persephone Vintage ($65). Which one to choose?
