From the Jenny Yoo website:
"The Voletta features a scooped strapless lace bodice over organza and taffeta. Princess seamed bodice ensures a flattering fit. Taffeta band at empire waist defines and accentuates the narrowest part of the waist. Layers of lace fall asymmetrically along a tiered tulle/organza skirt. Full length. Fully lined. Center back zipper."
I loved wearing this dress, which I found to be the perfect combination of beautiful and delicate (the asymmetrical lace is lovely) and very comfortable (no concerns about top falling down while dancing).
This dress was professionally dry cleaned immediately after wearing and has been hanging in a specialized garment bag ever since. There are NO stains or other signs of wear on the dress. The lace is intact.
