I like to focus on getting my skin right. So if my skin is behaving itself then I don't bother with a base. If it's just ok, I'll wear some concealer and tinted moisturiser. If I think it's looking bad, I'll put on foundation instead of tinted moisturiser. I'll also wear foundation if I want a more polished look. Meow Cat Glow highlighting powder is a godsend for looking radiant and alive.
Otherwise, I'm fairly simple. I like focusing on my cheeks and/or lips, so I'll wear bright, intense blush and/or red lipstick.
I prefer to leave my eyes bare or neutral apart from mascara; Kitten, Shroom and Satin Taupe are pretty much the only eyeshadows I use. I like a nice, thickish, defined, natural-looking eyebrow.
My favourite face is really good glowing skin, a bit of highlighter, bare or shimmery neutral eye, a touch of bronzer, a slight colour in the cheeks, and bold red lipstick.
