The first time a star wore H&M to a high profile awards show, it was Michelle Williams at the BAFTA Awards, and we were all a bit shocked. Then Ginnifer Goodwin gave it a go at the White House Correspondents dinner, others followed in Topshop at the MET Gala, and it almost became commonplace to find things like the Swedish brand's eco-friendly 'Conscious Collection' collaborations on the red carpet.

But we still weren't really expecting to see high street on an Oscar nominee, so when Helen Hunt excitedly explained she was wearing H&M, it was a pleasant surprise. Though this is obviously not an off-the-rack design we can pick up for £20 tomorrow, it's still a far cry from the one-off couture a lot of the other nominees chose to wear. These red carpet moments seek to raise awareness for H&M's ethical initiatives, but also prove that you don't have to spend thousands to look like a movie star. Of course it helps if you're Helen Hunt.

The most interesting thing about this dress is how similar it is to Reese Witherspoon's Louis Vuitton number. Both are blue satin, strapless, with dramatic trains. But can you tell the difference between the high street and the high end?
