Where else do you get every major Oscar star and fashion’s most powerful names all together on one red carpet? At the Met Gala, of course, and I was there to follow this magic event for you, my little Fashionistas! The Met Gala is often called Fashion’s Oscars, but honestly, I think it’s bigger than that!

This year, fashion’s finest are celebrating Miuccia Prada as well as Elsa Schiaparelli, who together comprise the Costume Institute‘s new exhibition, “Impossible Conversations.” The Fashion World had to wait until 2012 to participate to this chat  between the two pioneering figures of Italian fashion design.

The Impossible Conversation takes place via their works inside the Costume Institute of New York’s Metropolitan Museum of Art, where Anna Wintour, Miuccia Prada and Carey Mulligan are welcoming the most glamorous stars on Earth at tonight’s Costume Institute’s annual ball. 

So who’s showing up to fete Prada, Schiap and all of fashion’s finest?

Beyoncé caused a frenzy with her decadent purple feather train from Givenchy 

Scarlett Johansson rocked a beaded dress that clung to every curve in her Dolce&Gabbana

Jessica Alba glowed in a stunning metallic gold Grecian dress by Micheal Kors

Rihanna boasted a trim body in this slinky black Tom Ford gown

Ashley Greene showed off an incredible sweeping train from Donna Karan

Cameron Diaz glittered in a fitted backless Stella McCartney gown

Gwyneth Paltrow flaunted her toned back in a Prada silver blue dress

Coco Rocha captured all the paparazzi in a neon outfit by Givenchy

January Jones stole everybody’s attention in a zingy yellow Versace dress that showed off her curves

Rosie Huntington-Whiteley flaunted her natural beauty in a Burberry

There were also a lot of Fashion Couples like Sarah Jessica Parker and the legendary Valentino

or Chanel Iman and the handsome Tom Ford

A “strange couple”, like Emma Stone and Lanvin’s genius, Alber Elbaz

A less “dynamic” duo, as Lana del Rey and Altuzarra

The statement couple: Christina Ricci & Thakoon

The glamorous duo: Hilary Swank and Micheal Kors

and then there were also – the more interesting – Love Couples. The best one? Totally, Jessica Biel and Justin Timberlake, perfectly matching not only because of their Prada‘s outfits!

A laughing duo as Gisele Bündchen – in Givenchy – and Tom Brad 

and then the professionals, like the Jonas Brothers in Brooks Brothers

and the Gossip Girl stars: Ed Westwick, Leighton Meester (wearing Marchesa & Harry Winston) and Chace Crawford.
