Hmm... What that character is wearing is a short pile velvet in the deep purpley-red color that has been heavily embroidered with gold thread. You are NOT going to find fabric like that costume in any regular retail outlet, not a fully embroidered type anyway (short pile velvet is easy to come by).
Without seeing the fabric you are considering, it's difficult to say if I think it will work or not. Short pile velvet, especially once embroidered that much, tends to be pretty stiff, almost rigid. Some brocades are stiff, but a lot of the ones in regular retail outlets are pretty soft & floppy. I think the rigidity of your fabric is what will make or break getting away with different fabric. You can use lots of inner facing all over to bulk up and stiffen the fabric to change it's appearance.
