When Bloom is transformed into Dark Bloom, her eyes change color to gold, with piercing cat-eye pupils, and she gains dark violet eyeshadow. Her still-sparkling Winx outfit is a sparkly dark navy, cropped halter-turtleneck crop top decorated with an diamond-shaped purple jewel at the center of her chest, a matching miniskirt with matching-colored shorts underneath and high-heeled ankle boots. She also wears matching glove-like, detached sleeves around her forearms from the elbow to wrist with a point down the back of each palm and wears a small silver tiara with three sharp points at the top of her head. Bloom's hair becomes thicker, messier and a darker shade of red while her wings become more pointed and silver with gray tips.
In the Nickelodeon version, Dark Bloom wears the gothic clothing style - she wears navy black leggings and her outfit only changes color. The shapes of her brooch, tiara, boots and wings and her hair do not change.
