Her costume is vibrant and unique. It is a standout choice for cosplayers who love bright colors.
This guide will help you assemble a perfect DIY Ruby Gillman look. You will be ready for any convention or party.
The best part is that many pieces are comfortable for all-day wear. You won’t have to sacrifice comfort for style.
Ruby’s style blends seaside charm with high school fashion. It perfectly captures her shy yet powerful personality.
Complete Costume Breakdown
Ruby’s look is defined by her bright green and deep purple color scheme. These colors pop against her blue skin.
The silhouette is oversized on top and fitted on the bottom. This creates a classic youthful and quirky aesthetic.
Every piece of this outfit serves a purpose in telling Ruby’s story. It is a practical look for long events.
The colors are essential for character recognition. Stick to the specific shades of green and purple for best results.
Clothing & Core Pieces
The centerpiece of the costume is the oversized green turtleneck sweater. It should look a bit too big for you.
Choose a vibrant shade of green that matches the animation. A soft knit fabric will provide the right texture.
Under the sweater, Ruby wears purple rolled-hem denim shorts. The contrast with the green top is very important.
To complete the lower half, you need purple and grey striped sweater tights. These add a fun, youthful pattern.
The stripes help ground the look in the movie’s art style. Look for thick, opaque tights for the best effect.
Finish the core outfit with a pair of chunky purple boots. They should look sturdy and ready for a walk.
Accessories & Details
Ruby’s accessories are what truly bring the Teenage Kraken theme to life. Start with the light blue skin tone.
You can use light blue body paint for your face and neck. For your hands, gloves are an easier alternative.
Add grey leg warmers over your purple boots. This adds another layer of texture to the beachy style.
The hair is a dark blue, almost black, with a slightly messy texture. A wig with bangs works perfectly.
Don’t forget the prosthetic ears to mimic her unique kraken features. They should be subtle but visible enough.
The ears add that essential non-human detail that defines Ruby. Secure them well with skin-safe adhesive.
Cosplay Tips
When applying light blue body paint, make sure to set it with powder. This prevents it from smudging your sweater.
If you are uncomfortable with full body paint, stick to the gloves. It still gets the point across clearly.
Try to find a wig that has some natural-looking waves. Ruby’s hair has a bit of volume and movement.
For the boots, choose something with a platform if you want to match her animated proportions. It helps a lot.
Always wear your tights under the shorts to ensure everything stays in place. This also keeps you warm outside.
Check your makeup in different lighting to ensure the blue looks even. Use a sponge for a smooth application.
Character Vibe & Styling Notes
Ruby is often seen hunched over or looking slightly nervous. Mimic this posture in your photos for accuracy.
Keep your makeup simple aside from the blue skin tone. She is a student, so a natural look works.
Carry a backpack or a school book as a prop. This helps ground the character in her teenage setting.
Remember that Ruby is a kraken, so try to be fluid in your movements. Have fun with the theme!
Pose with a look of mild surprise or excitement. Ruby is constantly discovering new things about her world.
The “awkward teen” energy is the most important part of her character. Embrace the shy smiles and fidgety hands.
