Studio 17, the sister design line of Tiffany Designs, is known as a more affordable line that still includes the elaborate detailing and unique sophistication of Tiffany. Studio 17 Prom dresses range from fun and flirty short dresses to elegant full circle tulle ball gowns with shimmering, deep hues and soft floral pastels. Like it’s sister designer Tiffany, Studio 17 is also available in sizes 0 to 30 and with a look to make your prom dreams come true.
