How To Dress Like White Diamond

A White Diamond costume is all about a white outfit, dramatic cape and pale hair. These ready-made pieces give you a simple version of her Steven Universe look without sewing or building armor.

1. White bodysuit: Start with a fitted white bodysuit. The short sleeves keep the base simple and leave room for the cape to fall over your shoulders.

2. White tights: Add opaque white tights to carry the same color down to your feet. They also save you from painting your legs.

3. Starry cape: Drape the black celestial cape over your shoulders with the hood down. Its sparkling stars give you a ready-made alternative to White Diamond’s patterned cape.

4. Short white wig: Wear the white wig with the front brushed back and some volume at the sides. You can keep it simple for a party costume; recreating her exact star-shaped hair is an optional styling project.

5. White heels: Finish the outfit with white heels to match the bodysuit and tights. The block heels shown offer a wearable take on her shoes, or you can use white flats you already own.

6. Diamond gems: Place a clear diamond-shaped gem in the center of your forehead using cosmetic adhesive. The pictured gems give a small, subtle accent.

7. White body paint: Use white face and body paint on your face, neck and any exposed skin for her monochrome appearance. Follow the product instructions for application and removal.

8. Black lipstick: Add black lipstick for the sharp contrast that makes her smile so recognizable. Keep the rest of the makeup simple and let the white outfit do the work.

White Diamond Costume: FAQ

What do you need for a White Diamond costume?

Start with a white bodysuit, white tights, a starry cape and a short white wig. Add white shoes, a forehead gem, white body paint and black lipstick to finish the look.

Can you put together a White Diamond costume without sewing?

Yes. This version uses ready-made clothing and accessories, so you can assemble the outfit without sewing. The cape, pale hair and forehead diamond do most of the work in making the character recognizable.

How do you style White Diamond’s hair?

For an easy version, brush a short white wig away from your face and build volume at the sides. Her exact star shape needs more elaborate styling, but it is not essential for a casual costume.

Where does White Diamond’s gem go?

Her diamond is centered on her forehead. Position the gem vertically and attach it with an adhesive intended for cosmetic use.

Do you need full body paint for White Diamond cosplay?

No. The bodysuit and tights cover most of your skin, so you can limit the paint to your face, neck and arms. You can also skip the paint and keep the costume recognizable with the wig, gem and cape.
