I wore my Yoshitaka Amano-style Aeris for this photoshoot, too. I forgot to wear my official White Materia necklace like I did previously, stupid! Oh well, I guess bare neck is an interesting change since Aeris pretty much always has something around her neck, and in the particular Amano image that I used primarily as a reference for this costume she wears nothing around her neck anyway.
This costume is based off of Yoshitaka Amano's artwork of Aeris, who is an artist for Square and released official images of the characters with the original game. Amano's artwork was used as an inspiration for one of Aeris's alternative costumes in Final Fantasy Dissidia, but this costume references only the original artwork and my own imagination to fill in the gaps, so to speak.
