Eva Longoria's above-the-shoulder bob is simply the result of a tucked-up chignon and long layers left out in front. We love the gorgeous illusion, if only for today.

Pin-straight or lightly waved, there's no texture that doesn't work with this effortless cut.

Try on Anne Hathaway's many cute hairstyles now! 06 of 20 Liv Tyler's Silky Curls Steve Granitz/WireImage THE STYLE Loose, shiny curls parted in the middle WHERE The Super premiere in New York City INSIDE SCOOP Liv Tyler's hairstylist David Babaii worked a few drops of Couture Colour Pequi Oil Treatment into the star's damp hair before rough-drying it, and twisting random sections around a curling iron. Applying oil before you dry the hair makes sure you get all the glossy benefits with none of the greasy downside. 07 of 20 Taylor Swift's Sweet Side Braid LE FLOCH/SIPA THE STYLE A twisty, simple braid pulled over one shoulder WHERE In Paris over the weekend WHY WE LOVE IT Taylor Swift's low-key braid works because of the roughed-up texture. (Too silky braids just fall out.) The single tendril on the opposite side lends the look a bit of balance. Try on Taylor Swift's hairstyles now! 08 of 20 Camila Alves's Shiny Curls Mark Woodworth/BFAnyc/Sipa Press THE STYLE Extra long spirals with a high gloss finish WHERE An Intermix/Rag & Bone cocktail party in Los Angeles WHY WE LOVE IT Because of their three dimensional shape, curls tend to have a matte finish. Not Camila Alves's version. If you want to give your tendrils a similar luminosity, infuse your strands with a shine serum before you style. That way, you get all the benefits and none of the crunch some curl-enhancing products leave behind. 09 of 20 Thandie Newton's In-Your-Face Bun Richard Young/startraksphoto.com THE STYLE A chunky bun piled along the hairline and positioned to the side just so WHERE The Louis Vuitton party for Sam Taylor Wood in London WHY WE LOVE IT It's not often that stars rock hairstyles we've never seen before, which is why Thandie Newton's innovative look was such a treat. The oversize, opulent bun has a fresh, springy vibe, like a gorgeous blossom.

The part stops at the center of the head so the rest of the hair can be brushed back in a sexy, Bardot fashion. Try on Sienna Miller's hairstyles now! 11 of 20 Katy Perry's Slick Bun A-way!/SplashNewsOnline.com THE STYLE An eye-catching top knot WHERE Promoting her fragrance in Germany WHY WE LOVE IT Katy Perry swept back her bangs and her waves for a striking and refined look. The off-the-face updo shows off her milky skin and her wide, saucer eyes. Try on Katy Perry's hairstyles now! 12 of 20 Blake Lively's Lived-In Waves Jason Kempin/Getty THE STYLE Long, golden blond strands with lived-in texture WHERE The 2011 BAM Theater Gala in New York City WHY WE LOVE IT Blake Lively makes having good hair look easy thanks to touchable waves, glimmering color, and an easy-going texture that we just can't get enough of. 13 of 20 Jennifer Lawrence's Falling Down Updo Dominique Charriau/WireImag THE STYLE Long, breezy layers in front and a '60s-inspired ponytail in back WHERE The Miu Miu Ready to Wear show at Paris Fashion Week WHY WE LOVE IT Jennifer Lawrence has a winning combination. Not only is the Oscar-nominee an unflinchingly talented actress, but she's also got tons of gorgeous hair. This undone style is less precise than the looks she rocked on the red carpet, but no less enviable. 14 of 20 Mila Kunis's Soft Strands CHANCE YEH/PatrickMcMullan.com/Sipa Press THE STYLE Touchable strands pulled onto on shoulder WHERE The Cosmopolitan Fun Fearless Males of 2011 Awards in New York City WHY WE LOVE IT Mila Kunis's hair is the perfect mix of sleek and lissome; sweeping it to one side adds an easy dose of purposeful finish. Try on Mila Kunis's hairstyles now! 15 of 20 Amanda Seyfried's Deconstructed Updo Jason Merritt/Getty Images THE STYLE A crimpy updo that was more down that up WHERE The Red Riding Hood premiere in Hollywood WHY WE LOVE IT Amanda Seyfried's hair just keeps getting better and better. Here, the undone texture and low twisty knot pair to create an unexpectedly sexy look. Try on Amanda Seyfried's many cute hairstyles now! 16 of 20 Sofia Vergara's Sexy Ponytail Jason LaVeris/FilmMagic THE STYLE A long, bumped-up ponytail on the back of the head WHERE The 42nd Annual NAACP Image Awards in Los Angeles WHY WE LOVE IT Long swooping bangs and exaggerated volume at the crown lend an alluring sophistication to Sofia Vergara's simple ponytail. Thanks to high-intensity shine, the retro-inspired look stays entirely modern. Try on Sofia Vergara's many cute hairstyles now! 17 of 20 Vanessa Hudgen's Mid-Length Cut Andrew H. Walker/Getty Images THE STYLE A one-length, below the collarbone crop WHERE 25 Park in New York City WHY WE LOVE IT Vanessa Hudgens made a name for herself with down-to-there strands, but that doesn't mean she can't rock a fresher, shorter crop just as sexily. The shaken-out texture and spicy highlights give the straightforward cut an edgy twist. Try on Vanessa Hudgens's hairstyles now! 18 of 20 Ginnifer Goodwin's Choppy Pixie Chelsea Lauren/FilmMagic THE STYLE A spiky, side-swept cut with lots of piecey texture WHERE The Dance for Equality Benefit in Hollywood WHY WE LOVE IT Ginnifer Goodwin's been rocking a short cut since 2009, but this most recent styling job by Anh Co Tran was more jagged and edgy. "The bottom is buzzed super short, but we've been letting it grow out on top-that length is what makes it such a versatile cut," says Tran.

We were so pleased to see this breezy down 'do, which further showcased how well the icy blond works with her warm skintone. Try on Emma Stone's many cute hairstyles now! 20 of 20 Kerry Washington's Straight Strands Mark Sullivan/WireImage THE STYLE Super sleek hair paired with thick, eyelash-grazing fringe WHERE The Vanity Fair Oscar party in West Hollywood INSIDE SCOOP Kerry Washington usually opts for low-key, rumpled waves. But according to her hairstylist Marcus Francis, her signature look wouldn't work with her graphic dress. "Her dress was very sleek with clean, straight lines. The hair needed to reflect that," he told us. "If Kerry had worn her signature waves, it probably would have competed with the dress, and that dress needed all the attention. Bone straight hair with blunt bangs drew attention to her cheekbones and almond shape eyes-two of the most important features to showcase."
