Here are some of the most well-known Ariels:
* Ariel from Disney's *The Little Mermaid*: She has long, flowing red hair, bright green eyes, a pale complexion, and a slender, athletic build. Her signature look includes a purple seashell bra, a green tail with shimmering scales, and a pink seashell necklace.
* Ariel from Shakespeare's *The Tempest*: This Ariel is a spirit of the air, so she doesn't have a physical appearance. However, she is often described as beautiful, ethereal, and magical. She is capable of taking on different shapes and forms to accomplish her tasks.
* Ariel from other adaptations: The depiction of Ariel can vary depending on the specific adaptation you're interested in. For example, in the Broadway musical *The Little Mermaid*, Ariel's look is more elaborate and theatrical.
