St. Pucchi

Style 9106 (1999)

"Amazingly, style 9106 is a gown that we still get a lot of inquiries on from our website," says designer Rani Totman. "I think brides are drawn to the traditional elements, like the cap sleeves, and the flattering A-line, as well as the light but rich silk organza fabric, which is suitable for almost any venue."
