The outfit she's wearing is her ceremonial dress.
Ivy, instead of being sent to Earth to earn her wings like most angels, was raised on Earth, half angel, and earned her wings by bringing back Dib. After that took place, whenever her eyes showed signs of her angelic power, she would get a horrible headache. In angel forme, her hair is the same as in this pic. #ivy #earn #wings #magic #angel #ceremony #divy #dib #dress #elements #whisperelements #weocref #divy
