10 Most Eye-Popping Met Gala Looks

High fashion was on display once again at the Met Gala Monday night, and it was all about avant-garde this year, in tribute to honoree Rei Kawakubo, the 74-year-old Japanese creator of the Comme des Garcons label. Some of the most talked-about looks at one of the ritziest nights on the calendar:

1. Kendall Jenner. She wore what USA Today calls a "visible thong": a daring La Perla Haute Couture Collection gown created from more than 80,000 crystals.
2. Helen Lasichanh. She was one of the guests who wore a Kawakubo creation, arriving in what the AP describes as one of the designer's signature "avant-garde, bulbous, and armless jumpsuits."
3. Cara Delevingne. Her sci-fi look included not just a brocade Chanel pantsuit, but what Vogue calls a "colored chrome" scalp: She recently shaved her head for her role in Life in a Year and arrived with her head sprayed with metallic silver paint, resembling a pixie cut.
4. Rihanna. She was another to wear a Kawakubo creation, and US Weekly is among those declaring her "queen of the ball" for being "flawlessly on theme" in her ornate gown of petal-like pieces.
5. Katy Perry. The co-host wowed in a custom Maison Margiela gown and headpiece, complete with a veil that appeared to bear the word "Witness," People reports.

6. Celine Dion. The singer, attending the event for the first time, caught the eye of the New York Daily News with her black and silver Versace bodysuit with an origami-inspired headpiece.
7. Rita Ora. She "was wrapped up like a gift in sculptural red bows over a pale pink tulle skirt," per the Hollywood Reporter.
8. Priyanka Chopra. She wore a floor-sweeping Ralph Lauren trenchcoat gown that "took up a lot of real estate on the carpet, which is actually blue this year," the AP notes.
9. Jaden Smith. Oddly, Delevingne's Life in a Year co-star appeared to be carrying the dreadlocks he let father Will Smith cut off weeks ago. "Perhaps this is somehow a rumination on the night's theme of Rei Kawakubo/Comme des Garçons: Art of the In-Between," suggests Hilary Weaver at Vanity Fair.
10. Lily Collins. In what was seen as an homage to Kawakubo, she wore a frothy pink Giambattista Valli ensemble and had a bob cut that Vogue notes had an "unmistakable likeness to the trademark haircut of the night's honorary designer."
