This category is predicted by retail analysts to grow about 25 per cent in the next five years and will most likely reach its peak when Beyonce releases her own line of "athletic street wear" for Topshop later this year. McCartney also this week released her new athleisure line, StellaSport, aimed at a younger audience. If you really want to keep up with the play, the year will also see the term "health goth" infiltrate the mainstream, much to the chagrin of dark poetics already sporting a leather Rick Owens snood to their ballet barre lessons.
