This year the theme for the Metropolitan Museum of Art's Costume Institute ball (Met Gala) was "Rei Kawakubo/Comme des Garçons: Art of the In-Between," inspired by the structured creations of the Japanese designer's avant-garde label.
It's the one night when celebs can be really creative and push fashion boundaries.
Fashionistas waited in baited breathe to see what pop princess Rihanna was going to wow them with this year.
She didn't disappoint when she showed up in a dramatic, ornate floral Comme des Garçons dress. She completed her look with a sleeked back top not, strappy heels and gorgeous pink shimmer eyeshadow.
Rapper Nicki Minaj wore a custom-made H&M red and black with a kimono inspired top which fell into a sweeping train. She showed off her curves and tiny waist in a minimalist bodysuit and an over-sized obi belt.
Zendaya couldn't go unnoticed and caused a social media frenzy in a Dolce & Gabbana gown which she wore with big hair.
We took a moment to appreciate Actress Zoe Kravitz who effortlessly wore a strapless pink and black Oscar de la Renta gown with an off-the-shoulder train.
But what would the Met Gala be without a few bizarre moments
Jaden Smith recently chopped off his dreadlocks and decided to accessorize his outfit with them on the night. I suppose he wasn't ready to let go of his locks.
Pop singer Katy Perry's attempt at avant-garde looked like a crimson bride with a long veil and train. The word "witness" which looked like "wetness" was embroidered on the veil across her eyes.
Reality TV star Kim Kardashian didn't even bother with this year's theme. Instead she wore a simple white dress by Vivienne Westwood. No accessories and NO Kanye West. Model sister, Kendall Jenner left little to the imagination by wearing a sheer slip "dress".
The memes popped up in no time when singer Pharrell Williams' wife Helen Lasichanh hit the red carpet in a striking red outfit.
Selena Gomez missed the memo regarding the theme and opted for a matric ball look instead.
