What a long, strange trip it's been: Though today's definition of perfect eyebrows is a thick set untouched by tweezers similar to Cara Delevingne's impeccable arches, things didn't always come so naturally in terms of brow trends.
Back in the 1920s, silver screen stars like Anna May Wong and Clara Bow wore theirs pencil-thin with a severe downward-curving tail, and every decade that followed saw its share of brow-raising trends that would come and grow in waves. Perhaps thanks to Audrey Hepburn's full set in the 1960s, arches began taking on a more natural appearance, until the '70s, when disco, shimmery shadow, and interesting brow shapes came on the scene.

Others, like Norma Shearer, grew their brows into a completely straight line, save for the down-turned tails on the far edges.

Dietrich's skinny set walked the line between the trends of the '30s and '40s, though her arch was less severe than those of the previous decade.

1950s: Eartha Kitt
Kitt's graphic arch followed the aesthetic of the decade, and added a slightly sensual feline vibe to her look.

1960s: Nina Simone
Like Hepburn, Nina Simone also wore her brows full, but with a rounded, emphasized arch.
1960s: Twiggy
With graphic eye makeup and lengthy lashes the focus of the look, those who followed the mod trend like Twiggy kept their brows groomed into an arch, but opted for thin, rounded tails to complement the statement liner.
1970s: Donna Summer
Chalk it up to the sparkly disco feeling that took over the nation, but in the '70s, a thin, curved brow like Donna Summer's allowed the shimmery eye shadow to extend even further.
1970s: Diana Ross
The sharp arch of Diana Ross's eyebrows gave her lengthy lashes an even longer appearance.
1970s: Pam Grier
Pam Grier's brows followed a more natural shape, but stayed in line with the thinner trend of the decade.

Following in the footsteps of her Madgesty, many women left out the tweezers entirely, allowing their arches to completely grow in.
1980s: Grace Jones
The fashion-forward crowd, including supermodel Grace Jones, emulated the look of a real-life Patrick Nagel painting by opting for graphic brows with a severe upward slant.

In contrast to the overgrown look of the previous decade, the '90s saw an abundance in pencil-thin brows, a la Kate Moss.
1990s: Mariah Carey
Not unlike the skilled vocalist herself, Carey's curved brows hit all the right notes in terms of the mid-90s trends.
1990s: Sherilyn Fenn
In addition to "Who killed Laura Palmer?" another question we had while watching the '90s-era cult TV show Twin Peaks was "Who does Audrey Horne's brows?" thanks to Sherilyn Fenn's trademark arches.
1990s: Tyra Banks
No brow powder here! Banks's light natural set was groomed into a narrow silhouette.
1990s: Drew Barrymore
The grunge era also saw some interesting shapes, similar to Drew Barrymore's skinny, ultra-dark arches.
2000s: Cameron Diaz
Recovering from the tweeze-fest that was the '90s, eyebrow shapes remained thin, but followed a more natural path like Cameron Diaz's.
2000s: Victoria Beckham
Instead of lining the beginning portion of the brow with the bridge of the nose, stars like Victoria Beckham had their arches start along the outer area of the nostril.
2000s: Mandy Moore
With frosty, early aughts shadow as the hottest trend of the moment, light brows like Mandy Moore's provided a subtle frame for the sparkly effect.
2010s: Kim Kardashian
Perhaps in an attempt to keep up with the Kardashians, or our natural hair growth cycle, the 2010s were marked by a more natural shape with a vibe that suggested bigger was better, at least in terms of our brows.
