Amy Smart is a knockout in red

We here at Secret Sales HQ love to see our favourite celebs support a good cause and the Environmental Media Association Awards was as good as any.

The world’s hottest A-listers came out in their finest to attend the bash in Los Angeles this week, which was held to celebrate the 20th year of the association - and it was one fashionable event.

Everyone from Alanis Morissette and Calista Flockhart to Sir Richard Branson and Blythe Danner was in attendance, but the celeb to leave the most lasting impression was actress Amy Smart.

The Starsky and Hutch star donned a super-sexy red figure-hugging designer dress with a thigh-skimming hemline and a cut-out panel below the bust, which she paired with some chic pale grey platforms and a demure black and white clutch.

Considering the sultry shade of the ensemble, it could have been a tad too racy given the tight nature of the cut, but I think the 33-year-old pulled it off with elegance thanks to her casual hairdo and muted makeup palette.

I have never been a huge fan of the colour red, but there are a few celebrities who manage to wear beautifully.

Eva Mendes is one in her favourite Dolce and Gabbana designs, Nicole Kidman is another and thanks to this little baby, Amy Smart can now join that category.

What do you think about this dress?
