Fairy Kei is a Japanese street fashion style inspired by children's clothing and pop culture of the 80s and 90s, particularly brands such as My Little Pony and Care Bears. It typically features pastel colors, graphics on clothing, and oversized clothing. Common motifs in Fairy Kei include rainbows, unicorns, candy, confetti, balloons, cats, and stars.
Fairy Kei is associated with a larger aesthetic style known as "yume kawaii" (literally "dreamy cute"). As a result, you may sometimes hear this style be referred to as such instead.
