In the fourth episode of The Fashion Show shoes really are a girl's best friend. In the Harper's Bazaar mini-challenge, fashion and functionality unite with an eco-friendly challenge that asks the designers to create a new print for Olsenhaus pure vegan shoes. The elimination challenge tackles a common problem women encounter – falling in love with a hot pair of shoes only to realize you have nothing to wear with them. The contestants are surprised with a trip to the international mecca of jaw-dropping shoes, the Bergdorf Goodman shoe salon. Each designer selects an avant-garde pair of high-end shoes, and must design the perfect complimentary outfit to be worn with their killer heels.
