One source claims the 18-year-old was actually bullied for being there -- apparently not everyone thought she earned the right to walk the shows!
The insider spilled:
We hope she brought a Tide pen!
Rather than going for a vampy look, the former Smash star went for a virginal look in a long-sleeve white lace dress and nude slingbacks.
For some added pizazz, Katharine carried a pearl and beaded clutch in her black-tipped fingers and layered some necklaces around her pretty little neck.
We have to admit, the whole outfit is a tad matronly, but she still looks cute.
What do U think? Should Katharine have worn something seksier???
