Complete Costume Breakdown
Clothing & Core Pieces
The primary focus of this cosplay is the layered upper body clothing.
You will need a clean white collared polo shirt with short sleeves.
This shirt serves as the bright base layer for the entire outfit.
Select a polo made from cotton for the best comfort and fit.
Next, you must find a plain black sweatervest to wear over it.
The vest should have a V-neck to show the polo collar properly.
This specific combination is essential for capturing Sunny’s signature school-boy look.
For the bottom half, look for a pair of standard khaki shorts.
The shorts should be a neutral tan color to match the game.
Choose a length that sits just above your knees for proper proportions.
Ensure the shorts have pockets to carry your phone and other essentials.
This simple clothing set creates the foundation of your Sunny costume.
Accessories & Details
Sunny’s hair is one of his most recognizable and iconic visual features.
A short black wig with straight bangs is necessary for this look.
You should style the bangs to fall just above your eyes neatly.
Use a small amount of styling product to keep the hair flat.
For footwear, you will need a pair of white high ankle socks.
The socks should be visible and pulled up to their full height.
Pair these socks with classic black loafers or simple dress shoes.
The shoes should be polished to maintain the character’s neat aesthetic.
These accessories round out the costume and add a level of polish.
Attention to these small details will make your cosplay stand out more.
Cosplay Tips
Wearing a wig cap will help keep your natural hair hidden away.
Secure the wig with bobby pins to prevent it from sliding around.
If the polo shirt is too long, tuck it into your shorts.
This keeps the silhouette clean and prevents bunching under the vest.
Consider carrying a prop like a violin case for a deeper reference.
A small white lightbulb prop can also represent the game’s themes well.
Practicing your poses in front of a mirror helps improve your photos.
Character Vibe & Styling Notes
Sunny is a character who often appears distant, quiet, and very lonely.
Try to maintain a neutral or somber expression during your photo shoots.
Slumping your shoulders slightly can help convey his shy and reserved nature.
Avoid using bright or heavy makeup to keep the look very natural.
A bit of concealer can help create a pale and youthful complexion.
The contrast of black and white reflects the game’s internal conflict themes.
Keep your movements slow and deliberate to match his introverted personality.
Remember that the vibe is just as important as the clothing itself.
