It's not a typical weapon of choice for violent offenders, but a high-heeled shoe came in handy for one misguided woman who wielded the dangerous accessory outside a Brisbane nightspot.

Sophea Tun, a 21-year-old mother of two children, faced Brisbane District Court today over a stiletto attack on a Canadian student outside the Chalk Hotel at Wooloongabba last year.

The court was told Tun, a beauty therapist hopeful, was with a group of friends outside the popular drinking spot in the early hours of September 6 when 27-year-old Tammy Hinchey, in Australia as a student, asked them why they were yelling in the street.

One member of the group, identified in court as only as Sharon, took offence to the question and used her high heel shoe to hit Ms Hinchey over the head, Crown prosecutor Amanda Meisenhelter said.

When Ms Hinchey called Sharon a "bitch" Sharon assaulted her again and this time Tun joined in, arming herself with another shoe and striking blows across Ms Hinchey's scalp.
