I feel the secret to Mary Kate's sultry look is how she uses eyeshadow on both top and bottom lids-
Pick a couple of shadows, a deeper tone and more mid-tone.
I used several shades of brown.
Be armed with a quality brush- I used i.d. Bare Escentuals multi-tasking liner brush for both shadow and liner-
Start with minimal makeup, not including concealer.
(You'll want to do concealer last to avoid shadow fall out and an overall mess.)
Do a basic line on top, and an even coat of a base shadow over the lid-
Take your eyeshadow that's the medium shade and apply all over the lid,
and thoroughly under the lid-
Now, take your darker shade and lightly line the bottom of the lid and fill in the crease areas of your eyes-
You'll want to use a pencil liner to fill in the upper and lower parts of the eyelid- Be sure to get it in the rim, where your lid is semi-wet.
Take a q-tip and gently soften the edges of where you placed your shadow.
You want everything to be blended, not harsh.
Apply under-eye concealer. Make sure the area is free of any fall out eyeshadow, and avoid the area you placed your shadow underneath the eye.
Last, you're ready for mascara-
Don't be shy.
And there you have it! Soft, smokey, sultry eyes!
See the difference?
