The uniform has a male and female version that share the shame overall color scheme and design. They are based on the commonly seen Japanese school uniforms which in turn are modeled after European-style naval uniforms.
Both the male and female version have remained relatively unchanged for almost two decades.
The male uniform consists of a long loose white shirt that is tucked in neat black pants and held up by a brown belt with a bronze-colored buckle. The shirt has a breast pocket on the left side and is tied at the neck with a maroon-colored tie with two distinct v-stripes. An earlier version of the tie (seen in the Origins series) has a double v-stripe. There are large buttoned black cuffs on both sleeves, decorated with a white stripe. This same stripe is also seen in black on the sharp white folded collar around the neck. Males wear black socks in either brown outdoor shoes or white with mint-colored sandals (uwabakiWP) indoors.
The female outfit shares the male version's cuffs, shoes, collar, tie and shirt (sans the breast pocket). Girls wear a loose red mini skirt instead of pants and a black suspended top over the shirt, shaped similar to a corset. The earlier version of the skirt is worn higher and over the white shirt instead of under. It also includes a gold rim near the bottom edge. The suspended top is worn over the shoulders using two straps with metal clasps that lock with small round snap fasteners that are somewhat suggestively placed over both breasts. The clasps differ in the earlier uniform design. Black socks are worn thigh high on the legs with a decorative white line near the top.
Some senior male students wear a green armband on their uniform and act as school prefects.
For their school supplies, students typically carry a black briefcase. Females are also seen wearing a small backpack.
The Academy also has several outfits for students engaging in sports activities.
Seen only in a female variant, the one-piece swimsuit used by the school's swim team has a blue and white color scheme. It also shows a small distinct blue circular logo on the chest. Some suits seen in the Bible Black games also have an illegible text under the logo. This possibly denotes authority, as the text is only seen on swim team captain Shinobu Kobayashi and her subordinate Mikimoto.
White polo shirts with colored wristbands are worn by some student tennis players. However, these might not be considered official school attire. Girls wear an off-white skirt similar in design to the skirt seen on the school uniform. Boys wear short pants in the same color. Twelve years later, the outfit is also seen in a mint and white color scheme worn by student Maki Kurimoto and a male student (seen in an episode of the Only series).
- The school uniform is one of the most recognizable parts of the Bible Black series. It has been recreated by many fans of the series and worn as cosplayWP at anime and other conventions.
- Another outfit that resembles the uniform can be seen worn by Jun and Maki in the first game (screenshot). This is possibly the uniform from their respective schools, as they are not seen as students of the Academy in the game.
