this aesthetic is known as kidcore. Mostly revolving around rainbows and colorful things, stuff that children would enjoy. Outfits would include many accessories such as belts, backpacks, kandi (lots of bracelets with cool designs you can look it up on google :3), rings, hair things, and more! Kidcore is an aesthetic where you just let out your inner child who loves rainbow, colors, and all things sparkly.
