Kidcore is mostly made of bright, often pastel, colors and kid like clothing.

Kandi jewelry is also common in this subculture. some people who make kandi call themselves kandi-kids. kandi can be a big thing in the rave scenes, many people do kandi trades at raves

Stuffed animals/those bags that look like stuffed animals are often carried. Fairy wings are also worn sometimes.

Stickers (like lisa frank stickers) are also used for decorating items and accessories.

Overalls, collared shirts, and those frilly ankle high socks, are more casual kidcore outfit items. These are often paired with kandi, stuffed animals, lots of blush, and sometimes cute bandaids on the nose.

Sanrio characters like my melody and hello kitty are also seen.
