The Met Costume Gala always draws a who's who of Hollywood and Monday night's bash, which showcases Miucci Prada and Elsa Schiaparelli, is expected to be one of the most star-studded yet.
The A-list attendees go all out for the glamorous red carpet event, wearing truly memorable designer ensembles. Here's a look back at the Met Gala's best of the best:
At last year's affair, which honored the late Alexander McQueen, Gisele Bundchen arrived in a jaw-dropping red strapless creation from the designer's namesake label.
Rihanna wore a surprisingly elegant lace Stella McCartney one-sleeve dress, which she accentuated with a long side-swept braid and sparkly green earrings.
Jennifer Lopez stole the spotlight at 2010's "American Woman" themed soiree, stepping out in a dramatic embellished Zuhair Murad Couture gown.
Blake Lively took a risk, opting for a sexy peacock blue Marchesa mini, while Katy Perry was impossible to miss in a dress tricked out with LED lights.
In 2009 the event was inspired by models and fittingly Kate Moss dazzled in a one-shoulder custom-made Marc Jacobs number with a matching turban by Stephen Jones.
Kate Beckinsale held her own amongst the supermodel crowd in an over-the-top Marchesa ball gown, as did Kate Hudson in a gold embroidered backless Stella McCartney dress.
