Out of the hundreds of shows that make up Fashion Month, there are bound to be some mishaps. Or, in the case of Gigi Hadid at the Anna Sui show on Monday, some wardrobe malfunctions. As the catwalk pro strut her stuff for the New York designer, one thing was missing: a shoe. The model handled it like a pro, though, thanks to a little help from sister Bella. As the models took their final walk, the Hadids can be seen holding each other as Gigi walks with just one shoe on.
