Interesting comments from someone familiar with the costume industry! Thanks for sharing.
Here's a better pic of Vidia in her wig, from the Disneyland version of Pixie Hollow. Disneyland's Pixie Hollow is outdoors under trees that offer semi-shade, so perhaps this more natural lighting gives a better look at the wig and costume? I'd love to hear your thoughts with the more natural lighting.
