Heather Graham was nervous at 'Hangover 3' premiere

Actress Heather Graham says she was not comfortable wearing the red carpet outfit that she wore during the premiere of "The Hangover Part III" in Paris, and so, she was nervous.

The actress usually opts for wearable and glamorous gowns with plunging necklines. But she felt out of her comfort zone in a high-necked monochrome Talbot Runhof outfit.

"This was such a couture dress. I was nervous. I've never worn anything like it before," femalefirst.co.uk quoted Graham as saying.

"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'," she said.

The 43-year-old said her new stylist, Tara Swennen, advised her to wear the dress and to tone down the rest of the look.

The actress 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.

"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'," she said.
