I haven't "officially" decided on a bouquet yet, but I fell in love with this one as soon as I saw it, and I thought it would go well with our colors- white with burnt orange and green accents (the bridal party will be dressed in burnt orange (and we'll have a few other orange accents here and there) and we're having the simply chic reception (mostly white with green accents))
It was actually designed by David Tutera too! However, it needs to be personalized a bit, so would like to replace the pearls that are in the light orange roses in the calla lilies with mickey pearls and have the orange jewels in the stephanotis flowers be mickey shaped as well. With a Disney wedding some things just need to be Disney-a-fide!!!

I hope they can do pearl and orange mickey jewels (I won't talk with Disney floral until July 2008 when we have our planning session.) I love the idea of hidden Mickeys!
Even though it's not final, I still wanted to share my idea. I hope that's ok!
