Ahead of tonight's Metropolitan Museum of Art’s Costume Institute Gala, we've rounded up three of our favourite looks from 2012.

The MET ball is one of the biggest events on the fashion calendar, and the stars usually save their biggest and best frocks for the event.

We can't wait to see who and what will be working the red carpet later today, so in anticipation, we've chosen our top star looks from last year.

For a full round-up of last year's looks, including who is wearing whose designs, check out our Met Ball gallery over on RTÉ Fashion here.

1. Emma Stone

Emma Stone never fails to delight on the red carpet, and how darling does she look here, dressed in Lanvin at the 2012 Costume Institute Gala. The actress is never afraid of standing out, and here she's taken a break from the ubiquitous floor-sweeper gowns, going for a fresh and young hemline that hit her just above the knee. This playful little number was embellished with crystal flowers and featured a voluminous skirt, without being in any way over-the-top. Top marks!

2. Carey Mulligan

Carey Mulligan stunned the fashion critics at last year's MET Gala wearing a futuristic Prada gown. This was a fantastic red carpet moment for The Great Gatsby star, and proved she's not afraid of standing out from the crowd. This gold and silver paillette designed number featured a halter neckline and A-line silhouette which enhanced the actress's tiny waist. A subtle quiff and dramatic black eye make-up finished off this dynamic look.

3. Camilla Belle

Camilla Belle is always flawlessly turned out, here she's gone for a particularly vampy, flapper girl inspired look in a silver plunge-neck evening gown. The beautiful actress chose a couture Ralph Lauren gown which she topped off with vintage art deco jewels. To finish off the very sleek look, she wore her brunette locks slicked back, while a dark berry lip complimented the dress to perfection.
