Luxe for Less
If you are a size 10 or under, you can get a high-end wedding gown with a lower price tag at sample sales. (Bridesmaids can get lucky at these sales too)
For example:
At The Wedding Shoppe in Wayne, there is a $4000 Carolina Herrera gown for $1600.
Another option is to look for your dress at a consignment shop, like Sabrina Ann in Ardmore, where the designer bridal gowns have been "once worn or never worn". Sabrina Ann carries gowns from size 2 to 18. They only accept clean dresses within 2 years old. Prices range from $400 to $3000.
