The aptly dubbed "Barbie Bandits" giggled through a $US11000 bank heist before hitting the mall for a shopping spree and make-overs.
Now one of the teenage girls has been sent to jail and the other is on probation.
Ashley Miller, 19, will have to serve only two years of a 10-year sentence and must complete the rest on probation. She pleaded guilty to theft and drug charges.
Heather Johnston, also 19, was sentenced to 10 years' probation for her role in the February 2007 heist in Acworth, northwest of Atlanta.
The two were caught on tape robbing a Bank of America branch in a supermarket.
They admitted to plotting with a teller to steal money and then spending it on clothes and cosmetics.
Judge Mary Staley urged Miller to consider her crimes and change her ways.
"I want you to correct yourself," Staley told Miller, a former exotic dancer.
"There's no reason you can't become a productive citizen when you get out of jail."
Benny Allen - who worked at the bank as a teller - was sentenced to 10 years, to serve five. Another teller who was involved in the plot, Michael Chastang, is yet to be sentenced.
During her sentencing hearing, Johnston took the witness stand and between sobs apologised for hurting and embarrassing her family and friends.
"A lot of people look down on me. I feel terrible.
"I want to set a good example for my little sister. She's a great kid.
"I don't want her to end up like me."
