What Wedding Dress I want

If I were able to design the dress, or have someone design one for me, it would have the following details:

Sweetheart neckline
strapless
full length
bead work around the bodice and trickles down
lace trim work
light weight
corset top (back laces up)
off-white (ivory, pale gold, etc)

Other than that I have no idea. I want it to be romantic and fun. I had thought I wanted a convertible so that I could be dressed down a bit for the reception, but the more I think about it the more I think "no one else is going to change. They don't expect the bride to, either."
