This small, super cute boutique was by far the best bridal shop I dealt with while planning my wedding. I had purchased my dress from a different shop in Philadelphia and I was desperately looking for someone else to alter my dress. A Bride's Design came to the rescue; they did a fantastic job and worked within my short timetable. The also have some great options for accessories like jewelry and veils and the line of bridal shoes they carry are surprisingly comfortable.
It's a small shop in the front of a historic Avon house (you park in the driveway) so they don't have a ton of inventory but what they have is high quality and reasonably priced. They carry a few designers as well and have their own line of dresses. They also custom-make dresses. The owner is so sweet and so helpful. I definitely recommend this place.
