Tulle or Taffeta for your Quince Dress?

Do you prefer tulle or taffeta for your quince dress. Taffeta is a shiny crisp, smooth woven fabric made from silk, and tulle is a lightweight, very fine netting, which is often starched. Both are nice fabrics. When it comes to taking pictures taffeta is a little trickier, since it reflects more light, the camera flash has a hard time but both fabrics look great, which one is your favorite?
