Platform shoe
While introduced in the early 90's platforms didn't pick up in mainstream fashion till the late 90's. This may be due to Naomi Campbell's runway fall in 1993 while wearing Vivienne Westwood's platform heels. After the 90's platforms did not pick up again till around 2003-2004 when YSL made a tribute sandal to commemorate the 70's shoe style. Many celebrities' liked this design for the added sex appeal.
