NEW YORK (AP) - Let the fashion policing begin.

The Olympics in Tokyo open Friday, when the world's athletes will march behind their flag-bearers. And when they do, the peanut gallery on what they're wearing will be open, too.

Olympic gear makes for lively social media fodder, starting with the hours-long Parade of Nations. The year-long wait due to the pandemic has given enthusiasts extra time to ponder what they love or hate.

There's the Czech Republic and its traditional indigo block-print design with matching fans, already the butt of some jokes. It follows the country's loud umbrellas and neon-blue Wellington boots of 2012 in London, along with its "Beetlejuice" stripes in Rio in 2016.

Israel's athletes have see-through nylon jackets with huge pockets, while Emporio Armani decked out Italy's team in track suits with a reinterpretation of Japan's rising sun in the colors of the Italian flag: red, green and white.
