Prettyman was born and raised in the town of Del Mar in San Diego County, California.
Prettyman began taking surfing as an elective at her junior high school at the age of 12.
She competed in the National Scholastic Surfing Association (NSSA) High School Division and earned fifth place in the state championship while still in middle school.
 She attended Torrey Pines High School in neighboring Carmel Valley.

Around the age of 15, Prettyman was given a mix tape of Ani DiFranco's music.
Prettyman began playing around with her father's old acoustic guitar.
Although her parents were initially angry with her for "taking" the guitar, they eventually became supportive of her interest in music.

Prettyman began playing in front of friends and an employee of the production company The Moonshine Conspiracy overheard Prettyman play and asked her to appear in the company's film Shelter.
Prettyman's song "Anything at All" was eventually featured on the film's soundtrack.
