Gigi Hadid sizzles in a figure hugging dress at the Guess Spring 2015 launch in Sydney

American model Gigi Hadid arrived in Sydney for the launch of the Guess Spring 2015 Collection, and sizzled in her black dress.

The 20 year old face of Guess sizzled in a figure-hugging dress that showed off her curves and featured a deep neckline that gave a hint of cleavage.

Gigi's dress also had a thigh slit and put her toned legs on show, and the model paired it with black stilettos.

A fierce orange lip colour and casual ponytail hairdo with loose strands framing the face completed her style for the event.
