The platinum-blond model wore a gold necklace, black platform heels and bobby pins in her hair with a smoky eye, E! Online reported.
The show, held at London's Vinopolis, wasn't an official part of London Fashion Week, but Hasselhoff told reporters she hopes plus-sized models will be considered part of the mainstream fashion world someday.
"Calling it 'plus-size' doesn't do it justice," she said. "It's about women with curves and women of all shapes and sizes. I just hope one day [shows like this one] will get the same respect."
