Topshop opened its Los Angeles flagship at the Grove with a Valentine's Day celebration that had a festival-like atmosphere.

Sports Illustrated went all out to promote this year's swimsuit issue, broadcasting videos of the featured models onto the exterior of the Caesars Palace in Las Vegas.

On Tuesday night, Bulgari celebrated Elizabeth Taylor's collection of its jewelry with an in-store bash in Beverly Hills. Designer Ben Bourgeois of J.

As a way to showcase 20 new fall and winter looks during New York's Fashion Week on February 7, Band of Outsiders created a scavenger hunt last week that combined a roving glass-paneled truck with Twitter.

On Wednesday, Adidas took to New York's Jacob K. Javits Convention Center to launch its new shoe-cushioning technology, Boost.
