This stunning emerald green Old Hollywood style satin gown from Unique Vintage (perfectly named The Harlow) is a slinky, silky, sexy, shimmery stunner. The color alone is swoon-worthy – that rich, lustrous and darkly brilliant green, though this dress actually comes in other shades as well. At their best, this style of 1930s inspired gowns fall like a waterfall and look like a dream. Gorgeous.
