Hughes won the junior title at the 1998 U.S. Championships in the 1997–1998 season. The following season, she competed on the ISU Junior Grand Prix and won the silver medal at the 1998–1999 Junior Grand Prix Final. She also took silver at the 1999 World Junior Championships held in November 1998. At the 1999 U.S. Championships, Hughes won the pewter medal in her senior-level debut. As the fourth-place finisher, Hughes would not normally have received one of the three spots for U.S. ladies at the 1999 World Championships, however, Naomi Nari Nam, the silver medalist, was not age-eligible for the event according to ISU rules. Hughes was likewise not age-eligible, but at the time a loophole existed for skaters who had medaled at Junior Worlds. Hughes was sent to senior Worlds and finished 7th in her debut.
