Curly v straight hair: which suits these ladies better?

Do poker-straight tresses or cute curls reign supreme in the celebrity hair war?
It's often hard to tell when the women in question look so impressive rocking both. As if the stars with cute curls don't give us #HairGoals enough, they often work straight, sleek and shiny styles with total ease as well.
Take Kylie Jenner, for example. The young star looks pretty and natural with tousled, voluminous waves, but also is not afraid of the hair straightener and rocks sleek hair like a pro. Her sister Kendall is no exception, being known for her shiny straight hairdo, and yet looking gorgeous when changing up her look and going curly.
See more stars who work both looks below - and decide which suits them best.
Getty ImagesThe ever-stunning Lily Collins showed off a new style on the 2017 Cannes Film Festival red carpet in the form of these gorgeous tight curls.
Getty ImagesHowever, she later appeared with ultra sleek, straight locks, in direct contrast to her earlier look. We can't decide which we prefer, as this straight 'do is absolutely wow-worthy, but her curls are a little different and more exciting.
Getty ImagesDespite being best known for her straight locks, Kendall Jenner looks natural and stunning with a slightly more voluminous curled style.
Getty ImagesBeing a true hair chameleon, however, means rocking both looks with equal ease, which Kendall always manages. As a model, the star is constantly changing up her look for shows, and looks just as stunning with straight, sleek locks.

Rex FeaturesKaty is another star, however, who is known for regularly changing up her look, and looks just as stylish with a straight bob accompanied by bangs, shown here.

Getty ImagesKristen Stewart's gorgeous textured pixie crop was made even better by some subtle waves.
Getty ImagesMiss Stewart is no stranger to more sleek, elegant styles however, and likes to opt for a slicked back straight style on the catwalk now and again.
Getty ImagesAnother Jenner sibling who is no stranger to tousled locks, Kylie Jenner is a total pro when it comes to curls. The star likes to add extra bounce and volume when wearing her hair like this.
Getty ImagesMore recently, however, Kylie has been styling her hair in straighter styles, as shown here. We think we prefer Miss Jenner's locks with a little curl and bounce, what about you?
Getty ImagesWe LOVE Sienna Miller's most iconic hair look: tousled waves with a touch of rough texture.
Getty ImagesWhile Sienna always gives us the ultimate hair goals, we're not sure we favour her choppy bob in a straight style as much as when it's curled...
