From designer website:
A modern-meets-glam style, this heavily-beaded mermaid wedding dress from Martina Liana is showstopping! Lace is hand-embroidered with beading, creating unique scroll patterns throughout the formfitting bodice and hips of this lace and tulle over regency organza mermaid gown. Modern, linear beading highlights the tulle straps and back of this style, giving it a completely-modern update. This linear detailing continues down through the full mermaid skirt, only adding to the drama of this style. The back of this mermaid wedding dress zips up beneath pearl buttons.
