I'll level with you; I've only seen 101 Dalmatians in its entirety once in my life, and not until I was 13 or 14. I didn't find it all that entertaining, and, in my opinion, it's a bit overrated. But there's no denying Cruella de Vil's mark in the world of Disney. She's something of a rhetorical figure - chances are you'll never run into someone who would dream of skinning 99 puppies and wearing them as a coat. Really, that's what we love about her as a character. That, and her slightly off-putting design.
I hope that's a really strong contour, and her cheekbones aren't just...like that.
1. Map out the cut crease.
After applying a primer and transition shade, use an angled brush to apply a black eyeshadow above the crease, starting above the inner third of the lid and flicking out into a wing over the outer third. Connect the edge of the wing to the outer corner of the eye and swipe a matte light brown shadow back and forth over the outline to blend it out.
I don't recommend making the line as long as this one was; I went back with a makeup wipe and shortened it later on.
To bring out the black, go back over it with either the same eyeshadow or a black pencil or gel eyeliner and smudge it out along the cut crease, concentrating the color in the outer half.
2. Fill in the lid colors.
Apply a white eyeshadow all over the lid, up to the black lines over the crease. Since white eyeshadow is pretty difficult to get pigment out of, either pack it onto an allover shading brush or apply it wet with a flat brush. I had to do the latter, and it wound up clumping up on my lid, but once it dried I was able to smooth it out with a clean, dry brush. Use the same white shadow on a dry fluffy brush to highlight the inner corner of the eye.
As I said before, I shortened my cut crease to keep it on the eyelid and farther away from the temple. After that, I applied the same black eyeshadow from earlier into the corner of the cut crease and blended it out with the light brown shade on a small fluffy brush. I also used the fluffy brush to blend the black and white shadows at the top together.
3. Tightline and add dots to the lid.
Use a black pencil or gel eyeliner to tightline the upper and lower waterlines, then use a black liquid liner to draw Dalmatian spots on the white eyeshadow (you can really use any black liner, but liquid might be more pigmented and require less pressure).
Use an angled brush to smudge the light brown shadow along the lower lashline, and connect the inner edge of the cut crease to the inner corner of the eye with it, blending the black and brown together to give the eyeshadow a more seamless finish. Highlight the browbone as you normally would, and finish off the look with a black mascara.
Once the eyes are done, do your face makeup as usual. If you're wearing this as part of a costume, I recommend a strong contour and red lipstick. Otherwise, it may be best to tone down the rest of your makeup and go with a nude lip instead.
