From memes to manicures, Olympians top fashion moments so far

We are less than a week into the 2016 summer Olympic Games, and we've already witnessed quite a few conversation-starter style happenings.

Some of the sporty goings-on were catwalk appropriate: supermodel Gisele Bündchen glamorously walking down the opening ceremony runway to Rio de Janiero's unofficial anthem (and Fashion Week favorite), "The Girl from Ipanema."

Others were trendy, albeit painful-looking: Michael Phelps and other swimmers appearing on TV Sunday with purple, circular bruises on their backs from cupping - a recovery therapy in which heated glass cups suction the skin.

There was even a meme-worthy optic: Phelps' mean mug as he waited his turn to swim while South African swimmer Chad Le Clos shadowboxed in his space.

But there were more fashionable moments:

Track and field runner Shelly-Ann Fraser-Pryce, 29, served as Jamaica's flag-bearer Friday night with bold yellow-to-green ombre hair. Talk about standing out. It was all so very shut-yo'-mouth, rainbow-hair-don't-care. Loved it.

Speaking of Olympic leaders, tae kwon do competitor Pita Taufatofua, 41, got viewers and Today host anchors all hot and bothered as he ushered Tongan athletes into the Games wearing his country's traditional skirt, his body glistening with coconut oil.

American gymnasts started their bedazzle Sunday in leotards covered in lightweight Swarovski crystals. Watch them glitter - especially 19-year-old Simone Biles - as they fly through the air.  On Tuesday night Biles helped the American women's gymnastic team - The Final Five - take home the gold. What's next for this history making team of totally stylish girl power?

The prettiest manicures belonged to the female swimmers. My favorite was the sunset-hued fingertips of Russian swimmer Yulia Efimova. But that's where my love ends, as Efimova has been linked to the Russian doping scandal. Efimova didn't get the gold during the 100-meter individual medley; American Lilly King did. (Who also sported quite the funky painted digits.)

Hungarian swimmer Katinka Hosszu's coach and hubby, Shane Tusup, was manbunned out while cheering his wife on to win the 400-meter swim Sunday and the 100-meter backstroke Monday.

In other poolside fashion news, American swimmer Kathleen Baker, 19, known for wearing pearl studs, lost one of her luminous earrings during Sunday night's qualifying race. A scuba diver recovered it, and the next day, Baker went on to secure the silver medal for the 100-meter backstroke.

Also on Monday, fencer Ibtihaj Muhammad became the first American to compete in the Olympics clad in a hijab. Muhammad, 30, from Maplewood, N.J., however, lost to France's Cecilia Berder.

It's also worth noting that not all female beach volleyball athletes are scantily clad. Egyptians Nada Meawad and Doaa Elghobashy, the nation's first Olympic beach volleyball team, wore long pants and shirts Monday, and Elghobashy, 19, became the first female Olympian to play the outdoor sport in a hijab.

Although the Egyptians lost to the bikinied Germans, fashion history was made.
