Dakota Fanning and Her Sister Are True Denim Queens

Elle attended a dinner hosted by Creatures of the Wind in a denim jumpsuit from the fashion house. She showed '70s class with a pair of platforms and a funky bag.

Elle paired her tied-up button-down with flouncy shorts in the same shade, completing her look with white sneakers, a Gucci bag, and a thin gold choker.

Take a tip from Elle and look for a style that's cinched at the waist and complete with simple accessories like a bright crossbody bag and flats.

Whether you wear them with chunky wedges like Elle or ballet flats like Dakota, the look you achieve is chic and polished for running errands.

Dakota ran errands in cropped denim, a cream sweater, and a black satchel.

Skirts like Dakota's are all over, and you can find one at any of your favorite retailers. Just choose the shade that most appeals to you and style your new mini with a breezy tank, ruffled blouse, crop top, or casual baseball tee — Elle and Dakota have tried it all.

Elle paired her denim mini with a cream ruffled blouse and Louis Vuitton purse.

Elle worked the same miniskirt with a striped tank and Converse.

Elle's also got a light-wash version of her denim skirt, which she wore with a baseball t-shirt.

Elle went for a high-low look by covering the top of her skirt with a loose gray tee and completing her outfit with her Louis Vuitton bag.

While you could go for a flared overalls silhouette, Dakota proves that the most flattering style hugs your curves and allows you to show off your shoes.

Elle's ultrafeminine crop top got a sporty twist from her pleated tennis skirt and white low-top sneakers.

Dakota worked her chambray dress at the airport, and we imagine her movable look made for a stylish yet cozy plane ride.

Elle showed off her curves by meeting her high-waisted Stella McCartney flares with a contrast denim 3 x 1 halter neck. She slipped on a pair of wooden platforms to achieve extra height.

Every girl needs a pair of denim shorts in her closet. You'll want to slip them on all the time, and you can dress them up or down by adding a few simple accessories. Here, Dakota showed off a polished look, while Elle twisted up her white tee and showed off her Calvins with her own cutoffs.

Dakota belted her cutoffs and cinched them at the waist with a belt. She completed her outfit with leather wraparound sandals.

Elle let her Calvins peek out from the waistband of her cutoffs, tying up her white t-shirt into a crop top.

Dakota worked her cutoffs with a go-to striped t-shirt while out with a friend.

Denim culottes are a need-now this season. Elle layered hers over a pink and white Solid and Striped swimsuit, which she worked as a bodysuit in Beverly Hills.

Dakota showed us why boyfriend jeans are perfect for the days you want to add a bit of cool-girl structure to your otherwise comfy look.
