Bronzino Eleonora of Toledo Dress Diary

I need to replace my old Florentine 1560s gown. It is too large, and when I tried to alter it a few years ago I discovered that I had run out of fabric and could not put the bodice back together. Fabric is available online now that makes me think I could make an attempt at Eleonora of Toledo's gown. Which one will my budget allow me to order? Do I watch my budget and order a print or do I throw caution out the window and order a woven silk?

I already have a version of this coverciere (related to the English partlet) - usually made of cords tied in a net-like fashion, and then beaded. I found a belly-dancers scarf that looks just the part.

The sketch below is from the Janet Arnold Book, Patterns of Fashion, 1560 - 1620 which I am using as the basis of my research.
