Sewing Dresses

Hello,
My father has generously offered to sew a wedding dress for me (yes he sews!). I am very excited, however I was wondering if anyone know any really good places to get bridal patterns?
I am going to look at Joann`s (our best sewing shop), but I want to look as much as possible. By the Bye, my favorite types of looks are Pronovias, Eden Bridals and Lazaro. Please email me and let me know since I`m a college student who travels too much to spend a lot of time on the net.
Thanks
Katy (khedgesg@oberlin.edu)
