How to put it together

1
Inflate a large exercise ball to use as a sizing mold, or prepare a pop-up laundry hamper as a flexible cylindrical base.
2
If making a disco ball, cover your spherical base with paper-mache or metallic silver fabric, leaving wide openings at the top and bottom for your torso and legs.
3
Attach self-adhesive mirror tile sheets or silver sequins across the entire surface of the sphere to catch the light.
4
Secure two thick elastic straps inside the top opening to drape over your shoulders like suspenders.
5
Put on a matching base layer, such as a silver unitard or black leggings and a long-sleeve shirt.
6
Step into the ball structure, pull the straps over your shoulders, and adjust for a secure, comfortable fit.

Makeup & hair

Keep hair sleek and pulled back in a high ponytail or bun. Apply silver glitter makeup, metallic eyeshadow, or face gems to match the sparkling disco theme.

Balls for couples, groups, kids & more

couples: One partner goes as a disco ball and the other as a 1970s disco dancer.
group: A full sports team lineup featuring a basketball, soccer ball, tennis ball, and baseball.
kids: A lightweight, plush fabric pumpkin or tennis ball costume that slips easily over warm clothes.

Tips

Ensure the leg opening is wide enough so you can walk, sit, and climb stairs safely.
Keep the structure lightweight by using foam, paper-mache, or inflatable materials rather than heavy plastics.
Wear a comfortable, breathable base layer underneath to prevent overheating inside the sphere.
