Hexy doesn't care for traditional garbs, she wears something arguably less flashy and more functional.
Although, she has determined a way to perform actual spells, her Book of Shadows also serves as a spell book, she has different Books for
different elements and types.
I really recommend this artist for those seeking commissions, his prices are more than fair and he has great turn around time.
The outfit is basically that of Soren in his arch sage outfit from Fire Emblem Radiant Dawn.
