Happy Birthday, Kristen Stewart! Shop the Star's Style Signatures

Kristen Stewart turns 23 today—and while avid Twihards are likely wondering how the star will be spending her special day with her co-star-turned-boyfriend Edward Cullen Robert Pattinson, we're just curious as to what she'll wear for the occasion. See, much as her beloved sneakers and slouchy tees have been maligned on the red carpet, you've gotta hand it to a girl who knows her signature style through and through. And it's not like K.Stew doesn't know how to dress up, either—in fact, the sheer lace numbers and slit-up-to-there gowns she wore to promote two of her recent projects, Snow White and the Huntsman and The Twilight Saga: Breaking Dawn - Part 2, definitely earned our stamp of approval. Her laid-back appeal even earned her an uber-lucrative deal with Balenciaga—no small feat for a big-screen vampiress.

Click through to learn which wardrobe staples Kristen swears by—sneakers and tees included, obviously—and to shop them all. Keep on keepin' it casual, girlfriend.
