Tony Awards 2015: Best dressed on the red carpet

Stage actress Kelli O'Hara dazzled in this prom-style Oscar de la Renta number at the ceremony, where she won 'Best Performance by an Actress in a Leading Role in a Musical' for her role in The King and I. Although it boasts a slightly more autumnal feel, we're big fans of the unusual colour Kelli opted for last night.

Anna Wintour never fails to wow at these red carpet events, but then... she is the editor-in-chief of Vogue. With her trademark bob in tow, Anna dressed her petite frame in this full-length shift shape dress, and we love how the light catches in all the right places.

Taking after her fashion forward mother, Anna Wintour, film producer Bee Shaffer also looked striking at last night's Tony Awards. The unique pattern on this Marc Jacobs gown more than makes up for its conservative design, covering her almost head-to-toe.

Amanda Seyfried broke the mould somewhat at this year's Tony Awards, opting for a playfully short Oscar de la Renta dress in muted gold and black tones. We're especially admiring how it elegantly cuts straight across her shoulders in a hugely flattering style. Finishing the look off with some Christian Louboutin shoes to die for, slicked back hair and a heavy smokey eye, all in all it's a gorgeously different look for the Mamma Mia actress.

We're sure mouths were dropping in envy at the sight of Australian actress Rose Byrne, famous for starring in the likes of X-Men and Bad Neighbours films. She rocked up to the Tonys in a plunging red Delpozo gown, with zip from top-to-toe, that many could only dream of being brave enough to wear. But Rose being Rose, she pulls it off and looks utterly fabulous.

Two-time Tony Award winning actress Judith Light chose to debut a white jumpsuit on the event's red carpet, as opposed to the standard dress. And we think it works a treat for her, accentuating her wonderful shape with a nipped waist.
