During her first engagement with the Buffalo Bill show, Oakley experienced a tense professional rivalry with rifle sharpshooter Lillian Smith. Smith was eleven years younger than Oakley, age 15 at the time she joined the show in 1886, which may have been a primary reason for Oakley to alter her actual age in later years due to Smith's press coverage becoming as favorable as hers. Oakley temporarily left the Buffalo Bill show but returned two years later, after Smith departed, in time for the Paris Exposition of 1889. This three-year tour only cemented Oakley as America's first female star. She earned more than any other performer in the show, except for "Buffalo Bill" Cody himself. She also performed in many shows on the side for extra income.
