"Sexy" is a foreign term to me; when someone tells me to be sexy, I just end up in stitches. I'm immature like that. Sex kitten makeup, however - I can do that! Several looks come to mind, but what I demonstrated here is more of a daytime sex kitten look - understated and soft, with pinky nude lips and a classic cat eye.

For the eyes, I started with a neutral base (MAC Bare Study paint pot) and then put a soft beige-pink (MAC buff de buff) in and above the crease, to give more contour. The crease color for this look can just be a couple shades darker than your natural skin color. Just pack the color in and above your outer crease, and blend with a fluffy brush. This part is all optional - it will look just fine without any shadow at all. But don't skip the primer/base!
The main attraction of this look is the cat eye. You can make this as subtle or dramatic as you want, simply by building upon the line, up and out. I wanted to do a video tutorial of how I do the classic cat eye, but two things happened: 1) I left my fluidline open and it dried out, making the process a little more cumbersome, and 2) I found this great cat eye tutorial on MAC's artists in action series. That's almost exactly what I do and use, except I prefer the Sonia Kashuk bent eyeliner brush, which has a very fine point. Either will do; it's just a matter of preference. I also do the line in shorter strokes, connecting as I go.
For the lips, I mixed two of my favorite lipsticks: MAC Pink Plaid and MAC Hug Me. Pink Plaid was a little too pink and matte; Huge Me a little too glossy and neutral. Together, they create a creamy, pinkish nude. Don't be afraid to mix your colors! I like to take a little of each and mix it on the back of my hand (you can also use a palette), until I find a color I like.
Note: If you have beauty marks, go over them with a wet q-tip or a little makeup remover, to take off the makeup. Let them show through!
