No doubt, women today are loving big, aggressive shoes. High heels, platforms, over-the-knee boots -- bring it on. But sometimes, there can be too much of a good thing.

On Thursday, 'Project Runway' season 4 winner (and the hit series' youngest champ), 25-year-old Christian Siriano, staged an otherwise fabulous show for Fashion Week. But his New York City audience gasped as his models stumbled in platform stillettos.

And the shoes didn't just trip them up momentarily. One model had to finish the show halfway unshod, and one leggy young lady in a feathered frock tumbled off her feet altogether, in a classic example of what 'Sex and the City' fans would surely recognize as "fashion roadkill."

Meanwhile, the designer says the floor, not his shoes, caused the model to take a dive.
