With the rottweiler being the muse to Riccardo Tisci's most famous work last year, this year follows the ferocious path with the shark. While rappers and ballplayers galore completely overdid the Rottweiler series, the Shark Sweater is headed toward the same fate. And at $510, it's not a cheap summer trend to adopt.
