Clefairy is a bipedal, pink Pokémon with a chubby, vaguely star-shaped body. A small, pointed tooth protrudes from the upper left corner of its mouth. It has wrinkles beside its black, oval eyes, a single dark pink oval marking on each cheek, and large, pointed ears with brown tips. A tuft of fur curls over its forehead, much like its large, upward-curling tail. Each stocky arm has two small claws and a thumb on each hand and both feet have a single toenail. There is a pair of tiny, butterfly-shaped wings on its back. Though incapable of flight, Clefairy's wings can store moonlight and allow it to float.

Clefairy is very shy and rarely shows itself to humans. On the rare occasions that Clefairy comes down from its mountain home, it can be seen dancing underneath the full moon's light. The area surrounding their dance is enveloped in a magnetic field. Once the sun starts to rise, it returns home where it sleeps nestled with other Clefairy. The anime has shown that Clefairy is actually an extraterrestrial Pokémon. Clefairy is known to be popular thanks to both its adorable look and behavior.
