Heather Graham was nervous about experimenting with haute couture on the red carpet.

The actress usually opts for wearable and glamorous gowns with plunging necklines, so felt out of her comfort zone wearing a high-necked monochrome Talbot Runhof number for 'The Hangover Part III' premiere in Paris.

She told People magazine: ''This was such a couture dress. I was nervous. I've never worn anything like it before.

''But I think of Paris as the home of couture fashion shows and people who wear really glamorous outfits. I thought, 'I'm going to dress up.' ''

The 43-year-old star confessed she had to be talked into the daring dress by her new stylist, Tara Swennen, who advised her to tone down the rest of the look.

Heather pulled her hair into a sleek ponytail and accessorised with an elegant Jacob & Co. bracelet, so as to not draw attention away from the asymmetrical neckline.

She said: ''It's hard to be objective about yourself; I'm really grateful that I have people giving me good advice.

''I thought, 'Wow, I love this elegant version of myself that I haven't gotten to express much in the past.' ''

Tara - who met Heather on the set of a Maxim magazine shoot - added: ''This dress was elegant and so fun! It had a Parisian chic vibe, so that's where we decided it should be worn.''
