Aquamarine Hoshino Cosplay Guide: How to Recreate the Cool Star of Oshi no Ko

Sharp-eyed and sharp-minded, Aquamarine Hoshino—better known as Aqua—is one of the most complex and compelling characters in anime today. As a reincarnated child star navigating the dark world of entertainment, Aqua brings mystery, melancholy, and a hidden fire to every scene of Oshi no Ko.

Cosplaying Aqua is about more than just his signature icy stare. It’s about embodying subtle emotion, hidden strength, and minimalist style with precision. This guide will help you channel Aqua’s energy through costume styling, colored contact lenses, nail details, and more—perfect for cons, photoshoots, or group anime cosplays.

The Look: Dressing Like Aqua

Aqua’s wardrobe is understated but polished, reflecting his quiet presence and emotional distance. Whether you’re cosplaying his school uniform or his casual actor look, the key is keeping it clean, fitted, and cool-toned.

Option 1: School Uniform

• White Button-Down Shirt: A classic base piece with a crisp collar and slim fit.

• Navy or Black Trousers: Neat and simple—no flashy patterns or loud accessories.

• Red Necktie: A nod to Youtou High’s uniform. Keep it sharp and centered.

• Black Blazer (Optional): Worn in some school scenes, it adds formality.

Option 2: Off-Duty Actor

• Black Hoodie or Long Coat: Aqua’s casual wear leans dark and layered.

• Neutral T-Shirt or Turtleneck: Soft gray, charcoal, or white all work.

• Fitted Jeans or Dark Pants: Keep silhouettes slim and modern.

• Boots or Low-Profile Sneakers: Minimalist footwear that suits his mood.

Even in casual outfits, Aqua looks intentional. Go for clean tailoring and avoid overly bright colors.

The Eyes: Colored Contact Lenses to Capture Aqua’s Gaze

Aqua’s name isn’t just symbolic—his eyes are a brilliant aquamarine, often glowing with emotion or hidden intent. It’s one of the most defining parts of his appearance, and colored contact lenses are essential to nailing the look.

EyeCandys Lens Recommendations:

• Aquamarine Blue: For an exact match with the anime’s palette.

• Teal or Blue-Green Circle Lenses: Add enlargement and intensity, perfect for that anime-eyed look.

• Icy Blue or Light Sapphire: If you prefer a slightly cooler tone for photoshoots.

Circle lenses with a crisp limbal ring will help enhance Aqua’s wide, piercing gaze. Look for lenses with a soft gradient or shimmer to capture his emotion-filled expressions.

Wear glasses IRL? Swap them for EyeCandys' clear prescription contact lenses so you can stay in character and see clearly throughout your event.

Hair: Aqua’s Signature Fringe

Aqua’s hair is dark blue-black and slightly tousled, with a long fringe that often falls over one eye. It’s not styled to perfection—but it still looks effortlessly cool.

Wig Tips:

• Choose a dark navy or black-blue wig with soft layers.

• Trim the bangs to sweep diagonally across your face.

• Use styling wax to lift the fringe or add texture without making it stiff.

• Tuck the sides gently behind your ears or let them fall naturally.

If you’re using your own hair, add temporary color spray or blue highlights for accuracy.

Makeup: Subtle and Realistic

Aqua doesn’t wear makeup, but you can use light techniques to sharpen your features and enhance your expressions—especially for cosplay photos or stage lighting.

Keep It Natural:

• Base: Apply a matte BB cream or foundation to even out your skin tone.

• Brows: Lightly define and shape to frame your eyes.

• Eyes: Tightline with black or dark brown eyeliner for depth. A touch of light gray or taupe eyeshadow helps define without looking overdone.

• Lips: Use a sheer balm or lip tint—something just enough to avoid a washed-out look.

If you’re recreating emotional scenes, consider adding a soft under-eye shadow or shimmer to mimic his expressive, tear-filled stares.

Nail Styling: Clean, Sharp, and Character-Accurate

Aqua wouldn’t be caught with flashy nails—but that doesn’t mean you should skip them. Hands show up in photos, and small details make a big impact.

EyeCandys Gel Nail Sticker Picks:

• Clean Buffed Look: Keep nails short and shaped for authenticity.

• Semi-Transparent Teal Accent (Optional): Add a single aquamarine-toned nail for a stylish nod to his name.

• Matte Black or Navy Tips (Stylized Cosplay): If you’re doing a fashion-forward or fan-art version of Aqua.

EyeCandys' semi-cured gel nail stickers are easy to apply, con-safe, and remove cleanly when you're done being dramatic for the day.

Props & Extra Details

Aqua’s look is subtle—but props can add storytelling depth to your cosplay. Try:

• Script or Clapperboard: He’s an actor, after all.

• Photo of Ai Hoshino: An emotional touch for dramatic recreations.

• Starry Eye FX (Advanced): Use light face paint or eye decals to mimic the iconic Oshi no Ko star shape.

• Matching Cosplay with Ruby or Kana: Perfect for group or couple cosplays.

For added impact, practice Aqua’s body language—calm, observant, slightly withdrawn but always calculating.

Final Touches: Cosplay with Emotion

To truly embody Aquamarine Hoshino, focus on more than the clothes—channel his mood. Aqua often stands apart, deep in thought, with a slow, deliberate presence.

Pose Ideas:

• Looking out of frame, expression unreadable

• One eye covered by your fringe, arms folded

• Holding a script or phone with narrowed eyes

• Side-by-side photo with Ruby, Kana, or Akane for drama
