4. Nicolas Ghesquière, designer
Trying to figure out Nicolas Ghesquière’s next step has become the party game of the season, after the acclaimed French designer parted ways with Balenciaga following a creatively charged 15-year tenure. Whether he decides to launch a signature brand or takes the helm of another fashion house, Ghesquière remains one of a handful of designers capable of producing both high-brow conceptual clothes and spawning a thousand high-street imitations. His spring 2013 collection, which proved to be his swan song, was widely praised by retailers and editors for its fresh and youthful tailoring, modern frills and square-heeled shoes.
