Here is why this year's Met Gala fashions were so crazily over the top

APTOPIX 2017 MET Museum Costume Institute Benefit Gala
Rihanna attends The Metropolitan Museum of Art's Costume Institute benefit gala celebrating the opening of the Rei Kawakubo/Comme des Garçons: Art of the In-Between exhibition on Monday, May 1, 2017, in New York.

This year's  Met Gala -- hosted by Anna Wintour, Katy Perry, Pharrell Williams, and power couple Gisele Bündchen and Tom Brady -- saluted Comme des Garçons' creative director Rei Kawakubo.

The Japanese designer is known world-wide for collections of clothing so billowing and elaborate they are more like origami than things to wear. Kawakubo's take on the classic white shirt is my favorite because she takes the classic staple up so many notches you forget it's a basic. Functionality takes a back seat in the Comme des Garçons over-the-top fashion world.

Kawakubo opened her design house in 1969, and her architectural women's wear has lived in the closets of the most fashion-forward celebrities from Lady Gaga to Sarah Jessica Parker. The Commes des Garçons runway show is a Paris Fashion Week showstopper.

To date, the 74-year-old Kawakubo is only the second living designer to have an exhibit in the Metropolitan Museum of Art during her lifetime. (The first was Yves Saint Laurent back in 1983.) And in this current climate of creative director musical chairs, she's among the handful of designers to remain at the helm of the fashion house she built from scratch. That's beyond commendable.

So on Monday night, fashion's dignitaries and Hollywood celebrities wore what industry insiders would joyfully describe as artistic fabulousity  -- but what the rest of us would likely consider odd.

The red-carpet ensembles were an undeniable nod to the amazing yet unwearable as well as a conscious shoutout to the very different. From Serena Williams' green Versace-clad baby bump to Janelle Monae's feathery Ralph Russo to Rihanna's floral Comme des Garçons cray cray, the night was also a glitzy reminder that fashion is much more than getting dressed. It's also salute to beauty, creativity, and, yes, fun.
