If it ain't broke, don't fix it!

That seems to be Jennifer Lawrence's motto as she travels the globe looking all movie-star glam while promoting The Hunger Games.

Just after the 21-year-old actress rocked a gold lamé Prabal Gurung gown with a sexy back and long train to the movie's huge L.A. premiere, she walked the red carpet in London today in yet another metallic dress.

The muted gold halter gown by Ralph Lauren fits Jennifer's gorgeous bod like a glove. And although she's gone for lighter eye makeup, her hairdo is styled exactly the same way into a loose updo.

Which golden-girl style do you prefer?

And do you think it was a good move to stick to a palette that works, or should she really have switched it up and dazzled us with an altogether different ensemble?

Weigh in below!
