I decided to be a rust colored cat with spots, but you can change up the color of the eyeshadow and lipstick to suit the color of your cat costume. I'll have recommendations for different colors below the instructions.
I started out with a light layer of my normal foundation, but then I blended a layer of cream bronzer around the edges of my face and down my neck to deepen my skin tone a little. Then to add depth back to my face I contoured a little under my cheeks with a powder bronzer.
Moving on to the eyes I started out by priming my lids up through the brow underneath my eyes and the surrounding area. To get my lid color I mixed a bronzy gold with a dark red orange to create my rust colored cat shade. I sort of out lined where I wanted the wing to be, and then filled in the lid. Then I cleaned up the shape with a nude colored shadow. Add black mascara, to you top lashes only. Now cats don't have eyebrows, however my eyebrows are SUPER blond so I filled them in a bit so it didn't look weird, but I imagine you normal people with eyebrows could probably get away with not doing them. ;D
Then taking black gel eyeliner on an angled brush I made a fairly thick wing then brought it in to the corner making the cat like dip in the inner corner. After that I took a white shadow pencil and lined my water line and just under connecting it to the corner of the liner in the inner corner. Then I outlined the the white with more black liner to complete the eye shape. Underneath I added more of the rust color (I used less of the bronzy gold though) and extended the cat eye shape.
The spots are totally optional, but I took a bronze cream and pretty much just added random spot to start out with. Then with a much smaller liner brush then I used before I took more gel liner and outlined the spots. I added a few small spot with just black to fill the space in a bit too. You could probably do the black with just pencil liner if you prefer. Then draw on your little whiskers.
I couldn't find a lipstick that matched perfectly, so I applied a sheer bronze lipstick and put a orangey gloss over it.
Tips for Different Colors:
Black Cat: I suggest using a shimmery grey or sliver, not black. That way it'll suit your costume but the liner will still be visible.
Tiger: Do stripes instead of spots.
White Cat: Skip bronzer, just add a little contour and lots of highlight. Use white and or light pink eyeshadow.
