Jessica Chastain's fame has given her 'amazing' access to designer clothes.

The 30-year-old actress - who received an Oscar nomination for her role in 'The Help' - says one of the perks of her increasing profile is that fashion designers want to dress her.

She said: ''I now have more access, which is amazing. I've always wanted to wear stuff like this, I've just never been given the access. That's what has changed for me.''

Although Jessica - who has recently worn gowns by Vivienne Westwood, Balenciaga, Elie Saab and Georgio Armani - admits she avoids certain looks because she doesn't think she can carry them off.

The 'Tree of Life' star told People Magazine: ''I'm not a model, and everything looks better when you're six feet tall and you're gorgeous and rail thin.

''On the runway, everything looks better. I can't do [some] outfits Justice, so I will not go there.''

But having been included in Vogue's top ten 'Oscars Best Dressed' list for her Alexander McQueen dress, it looks like her style sense is serving her well.
