Your cake was one I loved also...I actually took it's design and another's and photo-montaged them together for our own one of a kind cake. There's pics on my blog if you'd like to see.
Thank you!!! My girls have their dresses from davids bridal it's called oasis. It looks totally different online than in person, but I love that color.
p.s. they have beautiful Alfred Angelo bridesmaid dresses in that colour called tealness... at least I think its pretty close.
