Weddings can be notoriously expensive. But thanks to the Delaware Breast Cancer Coaltion (DBCC), several hundred excited brides-to-be this weekend were treated to a designer gown extravaganza at the Sheraton Wilmington South Hotel, where some 800 couture and fashionable bridal dresses were offered at prices reduced by 75% or more. Dresses worth thousands by Vera Wang, Oleg Cassini and other popular designers cost only a few hundred dollars. The beauty and bargains brought tears of joy to some shoppers, who consider choosing the right dress one of the most personal and exciting decisions of their wedding. Proceeds benefitted the DBCC.
