I wore it once and have kept it in storage after dry cleaning, so it's in very good condition. Size 38 The color is not completely green, but closer to emerald green. I think it's an elegant shade of blue-green that suits any age. It's a design that can be worn at weddings and formal occasions. Dress One-piece Wedding Emerald Green
