Ami Mizuno is a teenage girl who has short, dark blue hair that reaches her neck, and blue eyes. At times, Ami will be seen wearing reading glasses. Like Usagi, she wears a standard Juban Public Middle School sailor uniform and later a Juban High School one.
Sailor Mercury's standard uniform consists of a white, chest-armored leotard, a blue sailor collar with three white stripes, a blue choker, a blue skirt with a white puffy belt sat above it, and light blue bows at the chest and at the back. She wears a pair of blue short heeled knee-high boots with white triangular borders, white gloves with three blue arm fittings at the ends that reach just below her elbows, and a light blue circular gem at the center of her chest bow. Unlike the rest of the Solar System Senshi (besides Sailor Pluto), her uniform is sleeveless, giving off the illusion of a swimsuit which is supposed to be reminiscent of Mercury's power over water. A golden tiara with a blue, oval-shaped gem is located on her forehead, and for earrings, she has three blue studs on either ear. Additional accessories include the Mercury Goggles, which she can summon at her own will by pressing on one of her earrings, and a speaker that extends from her bottom left earring.In Act 33, when Super Sailor Moon is awakened, the shape of the gem at the center of her chest bow changes into a heart.
As Eternal Sailor Mercury, her sailor uniform radically changed. Her leotard no longer has chest armor, and the gemstone in the middle of her tiara is star-shaped. Her earrings have a blue star dangling from a single blue stud. Her choker is v-shaped with a yellow star in the center. Her sailor collar has a singular golden stripe on it. The gem at the center of her chest bow is also star-shaped. In place of her shoulder pads are short light blue bubble-like sleeves with two blue fittings at the ends; they have somewhat of a translucent aspect to them. Her gloves are extended to reach her upper arms, and her skirt now consists of two layers; blue on the top and light blue on the bottom. Her belt is now made up of two ribbons, the bottom one being light blue and the top one being blue, the top one being very lengthy and extending past her skirt. Her back bow is now back to its original size, and her boots are now white and knee-length; they have larger heels and blue v-shaped borders at the top that have yellow stars in the center.
As Sailor Mercury, she retains her civilian appearance but wears a gold tiara on her forehead with a blue gem on front. Sailor Mercury's dominant color is blue as her Sailor Senshi form is in different shades of blue. Her sailor uniform is blue with two white stripes to match her blue skirt and her knee-length boots and both her front and back bow being light blue and have a blue brooch on her front bow. She wears blue stud earrings on both of her ears. Her knee-length boots are similar to both Sailor Moon and Sailor Pluto.
