Anthony Franco filed the lawsuit Friday in Los Angeles Superior Court claiming the sultry R&B singer had agreed to pay him $35,000 to design the entire wardrobe for the "Toni Braxton: Revealed" show.
Franco says he received a check, but it was returned for insufficient funds. He alleges Braxton and co-defendant Liberty Entertainment Inc. put a stop-payment on the check.
Franco claims he was eventually paid $20,000, leaving an outstanding balance of $15,000.
Braxton is best known for such hits as "Breathe Again," "You're Makin' Me High" and "Love Shoulda Brought You Home." She has starred on Broadway in "Aida" and "Beauty and the Beast."
Braxton's show at the Flamingo Hotel in Las Vegas began last August.
Braxton's publicist did not immediately reply Tuesday to a message left with her agent, Ben Bernstein, seeking comment.
