New York's Metropolitan Museum of Art's Costume Institute Gala is to fashion what the Oscars are to film. Everyone wants an invitation because it means you are Someone. Anna Wintour, the undisputed queen of the fashion universe, reigns supreme over the Gala which celebrates all things style like no other event on the calendar.

The theme every year makes the event what it is - attendees take their style cues from the theme making for some of the most dazzling and extreme fashion ever to be seen on a red carpet (or in fact IRL). Who can forget Rihanna's voluminous canary yellow fur-trimmed train by Chinese designer Guo Pei at the China: Through the Looking Glass themed 2015 Met Gala?

And this year's theme, Heavenly Bodies: Fashion and the Catholic Imagination, means the Vatican are involved. After all they're lending a ton of their most exquisitely crafted liturgical items to The Met for the exhibition of the same name, which will open directly after the Gala on May 10 (the Gala will be held on May 7 this year).

Ahead of the religiously-themed event and exhibition, this week the Vatican hosted an exclusive preview of the items slated to go on display.  According to The New York Times some of the biggest names in fashion including Anna Wintour, Donatella Versace, Pierpaolo Piccioli (from Valentino) and designer Thom Browne to name but a few, "...met with Vatican luminaries" in the Great Hall of the Palazzo Colonna to eyeball the exhibition.

Chief Vatican 'fashion' liaison (or "the Vatican's de facto culture minister" per The New York Times), Cardinal Gianfranco Ravasi hosted the event and wore red and black, the colours Ms Wintour also chose to don for the event - was it accidental or a fashion match made in heaven perhaps?

Either way, Wintour seems to be enjoying herself if the snaps from the preview are anything to go by, meaning the items going on display must be truly extraordinary. Start saving now, this warrants a trip to New York to visit The Metropolitan Museum of Art.
