The top left swatch (the largest one) is from an eBay vendor. It is the closest I've seen to the actual color of the robes which is a more dusty blue than royal blue. However, most people think of this costume as royal blue because that's how it most often photographs.
- The bottom left is from JoAnn's in a royal blue, but I think it is too dark.
- The top right is from SyFabrics in Royal Blue triple plush velvet.
- The bottom right is the Navy blue triple plush velvet from SyFabrics which is definitely too dark.
I think I might go with the Royal Blue from SyFabrics, even though it seems a bit too purple, just because it's fairly inexpensive, and readily available -which means that more people can purchase it and we can all match and look uniform. Sy also carries a lining fabric and poly/cotton fabric in Royal Blue that can be used to line the robe and create the inner garment, respectively.
