There's no denying Robert Pattinson has a certain something. Experts have tried to pinpoint the precise formula for his unique brand of awesome (unkempt hair + self-effacing personality = the man of our dreams?), but the magical recipe continues to allude. Being the benevolent blog that we are, we decided to aid the scientific community by asking someone who's got loads of personal insight—"Water for Elephants" costume designer Jacqueline West.

You see, Jacqueline gave Rob his favorite pair of 1930s underpants (no really, read all about it), and we figured, who better than the woman who dressed him (figuratively at least!) to give us some dish. Jacqueline spoke to us about Rob's cool style off set and how his physique was different than what she expected after seeing "Twilight."

"You know, he’s very casual. He wears jeans and hoodies and tennis shoes, but he has a really, really nice style," she said. "Everything is well selected, but he’s very casual. He is a jeans and T-shirt, sweatshirt kind of guy." In other words, totally our type (hear that Rob?).

Jacqueline also added that Rob cleans up "nicely" but that she prefers his "dirtied" up look in the flick.

"This movie, I used to tell friends, 'he really dirties up well.' We've all seen him...used to seeing him so scrubbed and clean in the 'Twilight' movies. It's great to see him dirty and sweaty and dusty and really in working clothes," she said (as if we needed another reason to go out and buy a ticket for the movie). "It was a nice transformation and it made him such a different person than the other films I've seen him in."

Speaking off those other films, Jacqueline said that she watched "Twilight" to get a sense of Rob's body shape but that it didn't really do justice to his physique.

"I didn't realize from the 'Twilight' movies how really manly he is. I didn't realize until I really met Rob in person how really manly I could make his wardrobe and that he would be able to wear it so well," she said. "I didn't know how big he is. He's really like a Gary Cooper or someone like that, he has incredible stature."

A manlier, dirtier Rob? Don't mind if we do.
