Kristen Stewart's stylist has to beg her to wear heels on the red carpet.

The 'Twilight Saga: Breaking Dawn - Part 2' actress initially resisted requests for her to wear glamorous outfits in favour of a more grungy look, and her stylist Tara Swennen admits it can still be a challenge to put her in a pair of high shoes.

Tara said: ''I clearly prefer a heel. I just think it photographs better.

''Regardless of it being any type of heel, I think it elongates the silhouette, which obviously you always wanna do, make them look taller and have that longer look. But it's part of her personality; I think it's fun when she does it. There are definitely times when I have to say, 'Please, please, please put the heel on just for me.' ''

While Tara does like her to put nice shoes on, she does always ''expect'' Kristen will change into other shoes halfway down a red carpet.

She added to New York Magazine: ''She'll always change into her Converse by halfway through a carpet, which is to be expected at this point, but she puts on the heels for me for the photos, God bless her.

''At the end of the day, I want my clients to be comfortable because I think it shows. She needs to put on her sneakers and that's alright with me.''
