Koichi Hirose’s outfit centers on a stylized take on the traditional Japanese boys’ school uniform, set off by exaggerated anime hair and distinct manga-inspired facial linework. The tailored dark green gakuran creates a neat, disciplined silhouette that contrasts with his upward-swept silver hair, reflecting his shift from an unassuming student into a capable Stand user during the events in Morioh.
Putting this costume together is relatively straightforward in terms of garment pieces, but it requires careful attention to shape and clean lines. Because the clothing consists of a simple two-piece uniform, the visual impact hinges on how well the jacket fits, how sharply the hair is sculpted, and the high-contrast accessories that frame the outfit.
The Gakuran Uniform
Koichi wears a standard Japanese high school uniform in a distinct deep green hue, featuring a stiff standing collar, long sleeves, and a single row of metallic buttons down the front placket. Selecting a dedicated set such as the Koichi Hirose Uniform ensures that the jacket and trousers share the exact same fabric color and weight, which prevents the mismatched tones that often happen when pairing separates from different sources.
The fit of the jacket should sit squarely on the shoulders with the high collar buttoned snugly at the neck, revealing only a hint of a white collared undershirt if you choose to wear one beneath. The accompanying trousers are cut straight through the leg. Hemming the pant legs to sit just above the footwear rather than bunching around the ankles preserves the tidy schoolboy appearance depicted in the source artwork.
Sculpting the Spiked Wig and Brows
Once his Stand awakens, Koichi’s hair adopts an upright, wind-swept shape that defies gravity. A pre-styled base like the Silver Spiked Wig offers the correct pale silver tone and layered fiber volume required to build this silhouette. Out of the bag, synthetic fibers usually need extra definition to hold their shape; sectioning the wig into chunky points, backcombing slightly at the roots, and applying a heavy-hold hairspray or styling glue keeps the individual spikes rigid and upright through hours of wear.
Hirohiko Araki’s distinctive art style relies on sharp, bold facial features that balance the voluminous hair. Koichi’s eyebrows are particularly expressive, rendered as dense, dark blocks rather than soft arches. Drawing in clean, angular brows with a Black Brow Pencil bridges the gap between your natural features and the illustrated character design, grounding the pale wig against your face.
Footwear and School Bag
Instead of typical dark school loafers, Koichi wears crisp white dress shoes that create a noticeable color break against the dark green trousers. A pair of White Dress Shoes matches the anime coloration and gives the lower half of the outfit a crisp finish. A quick wipe down before wearing them keeps scuffs from distracting from the clean lines of the uniform.
To round out the student appearance, carry a classic brown student bag over one shoulder. A structured Brown Backpack mirrors the book bag Koichi carries throughout his daily routines in Morioh. Beyond matching his on-screen appearance, it serves the practical purpose of storing personal items, wig maintenance supplies, and convention essentials without breaking character.
