A change of pace

Now that my mad Star Wars rush is over I have time to relax and turn my thoughts towards the summer. My next project must be a new dress for faire...I need an Elizabethan, NEED it I say!!! So anyway, I have until July 23rd which gives me nearly two months which means that I can breath and start the search for fabric. I'm roughly recreating this dress (love the color combination) and have an orange silk that will do, but am having an awful time finding the right type of blue. If anybody has seen anything anywhere that would work then please, please help me!
