Grandma showed me a couple patterns and one is pretty close to it all i gotta do is fix the neck to close in the back! So after looking thourgh the game gallary appretnly her dress is a pale ivory close to champagne. The lighting makes it more yellow.
Gold Colored, at least as I see it. Many cosplayers do it white, but it all depends on how you interpret the shading of the ballroom. I would say gold satin as the fabric.
Anyway, let me know what you come up with.
Well, let me know how yours turn out! :D I've never seen Esther before.
