Floral and Peacock Feather Beaded gown Peacock dress Peacock Feather Print Dress with Crew Neck 2X White Peacock feather dresses are colorful and beautiful! They have shiny feathers with bright blues, greens, and purples. When you wear a peacock dress, you look elegant like a graceful bird showing its Peacock cocktail dress could do without the feathers on the shoulder, but I would wear this for a fancy occasion.
