Hall began collecting gem sweaters in 2000 and, with the help of her fans, has since amassed over 400 different sweaters. Hall modeled these sweaters on the website gemsweater.com, garnering significant Internet traffic such that she was asked to appear on one of the final episodes of Unscrewed with Martin Sargent. In her 2004 TechTV interview, she stated that "about 65% of the comments" from the gemsweater.com message boards were related to a particular outfit of hers that included gold pants. She decided to form a band, Leslie and the LY's, with former classmates, capitalizing on the popularity of her gem-laden sweaters and gold pants. In 2005, her band released their first album, Gold Pants.
In 2006, Hall followed up with a second self-released solo record, Door Man's Daughter, and toured the globe in support of it. She was named one of the "40 Greatest Internet Superstars" by VH1. Later in 2006, she appeared with fellow Internet personalities Jay Maynard, also known as "Tron Guy", and Randy Constan, a Peter Pan impersonator, to take a stand in the "battle over Internet freedom" in favor of network neutrality.
In 2007, she teamed up with Dungeon Majesty to create the video "Willow Don't Cry".
Leslie's newest songs as of 2009 were "Craft Talk" and "Tight Pants (Body Rolls)". The music video for "Body Rolls" premiered January 17, 2009 at her show in Ames but has since been released alongside "Gravel In My Shoe". Her 2010 album, "Back 2 Back Palz", features these two singles, as well as 11 country music inspired songs.
On September 27, 2007, Hall appeared on the Nickelodeon children's show Yo Gabba Gabba!, to perform in the "Dancey Dance" segment of an episode titled "Scary". She appeared again on October 21, 2008 in the season two episode titled "Differences". In October 2010, she began making guest appearances with the Yo Gabba Gabba! live touring act.
In 2013, Hall appeared in the episode "Summer Camp!" of The Hub series The Aquabats! Super Show!, a superhero-themed comedy from the creators of Yo Gabba Gabba!, where she played a gem sweater-wearing camp counselor named Jewel, who happens to be a shapeshifting werebeast.
