GatsbyLady London Long Wedding Dress. Size 4. New.
From the Wardrobe Shop “Sophisticated and statement-making all at once, the Galina Gown in White is the luxe, laidback look you’ve been waiting for. Exquisite embellishments give this gown a subtle shimmer that is fabulous without ever being flashy. Add the figure-flattering fit, effortless feel, and elegant details, and you have a dress that is sheer perfection.”
The above says white but appears Ivory to me.
