Caroline is often seen wearing clothing that consists of a gothic or witchlike charm. She wears backless outfits consistently as clothing tends to irritate the scars on her back. Her skin is on the paler side due to being considered as a dark fey. She has short straight black hair cut into a bob style and bright blue eyes. She's approximately 5'8" but appears to be 5'10" in certain shoes she likes to wear. When working, she wears her school robes that are iridescent to reflect the likeness of the Feywild.
As a fairy, her wings are a deep royal purple taking the shape of hornet.
