ST. LOUIS (KSDK) - A national non-profit is parking its "Big Pink Truck" at the downtown Sheraton Hotel this weekend for its ongoing tour of bridal gowns.

More than a thousand designer and brand name wedding gowns will be sold at discounts between 25 and 85 percent, with proceeds going to support cancer patients and their families.

Gowns of all shapes and sizes and colors will be available courtesy of designers, manufacturers and bridal shops.

The Big Pink Truck will be unloaded Saturday morning, with a special VIP event taking place that evening. Brides-to-be are encouraged to line up outside the Sheraton City Center Hotel Sunday morning before the 10 a.m. opening.
