The silver screen muses of Hollywood’s Golden Age are remembered for much more than their movies. They left behind a legacy of style, beauty, and elegance that will be passed on from generation to generation. From the fiery blonde bombshell Marilyn Monroe to the regal, real-life princess Grace Kelly, these women continue to inspire us with their signature looks.

But to make sure they looked picture-perfect on and off the screen, the members of this elite squad relied on super sneaky beauty secrets. Today, we’re unveiling 5 of the best tricks to steal from the sirens!

1. MARILYN MONROE

Miss Monroe’s ruby lips were a big part of her sizzling image. But achieving that pucker took a lot of work—specifically, more than one color. To give the illusion of a fuller pout, Marilyn would use several shades of red: deep crimson for the outer corners and lighter cherry for the center. Perhaps this was the beginning of ombré lips? She would also top it all off with gloss for added dimension.

2. AUDREY HEPBURN

Nowadays, all it takes to recreate Audrey’s doe eyes is a good coat of mascara. But back then, the style icon had limited access to powerful formulas. So, to boost her long lashes, she reportedly used a pin to separate each strand individually. For a less dicey 2016 option, go for a disposable spoolie!

3. GRACE KELLY

The Kardashians brought it back into focus, but contouring is hardly new to the beauty world. Back in the day, Grace Kelly applied two kinds of blush to accentuate her bone structure! The princess-to-be would swipe one color underneath her cheekbones and dust a different shade over the apples of her cheeks.

4. VIVIEN LEIGH

Reportedly insecure about her thin bottom lip, Vivien Leigh turned to a makeup hack that is familiar to all millenials—overlining. To plump up her pout, she would draw lip liner outside the natural lines of her mouth and then fill in the space with lipstick. Now, that sounds incredibly familiar (we’re looking at you, Kylie Jenner).

5. GRETA GARBO

Celebrated for her regal bearing and “ice queen” image, gorgeous Greta focused less on her lips and more on that stare. To give her eyes depth, she would apparently apply white eyeshadow all over her lids, from the inner corners of her eyes all the way up to her brow bone. The effect was reportedly so stunning that even Marilyn Monroe absorbed it into her own makeup routine.
