My skin is already oily, but add the humidity and forgeddaboutit. I switched from liquid to powder foundation about a year ago and it did wonders for my skin. I started out using bareMinerals matte foundation in Fairly Light, but now use the less expensive, but just as effective, Physician's Formula talc-free mineral powder in Translucent Medium.
I'm all about a matte finish and Maybelline's Dream Matte Powder provides the best results for me. It's not cakey and I don't have to use a lot to get nice coverage. I use Sand Medium, which is just a smidge darker than my skin color.
I just recently found The Body Shop's Shimmer Waves in Blush. I mix the colors for a subtle sparkle, a little color, and a nice glow across the cheekbones. I also use it as an eyeshadow and brow bone highlighter.
I like plain old ChapStick because it's not goopy like lip gloss and provides moisture and shine. I've seriously been addicted to ChapStick since the first time I put some on in 8th grade. I keep tubes in almost every area (purse, desk, bathroom) so that it's never too far away.
It's rare that I wear lipstick, but when I do (does this sound like Dos XX commercial?) I like to wear Victoria's Secret Perfect Lipstick in Wish (light pink) or Rosebud (berry red). From looking at the website, it doesn't seem like they have the Perfect Lipstick line anymore :/
If I'm going for a casual, day look I wear Urban Decay's X - a peach shimmer with gold shift. Being a light-skinned, cool color tones gal, I usually can't get away with gold shades, but X is the perfect mix of pinky peach and gold that doesn't look harsh against my skin tone.
For bold-colored eyes, I stick with purples and blues that compliment my light skin and dark eyes. For this I love Anastasia's Pacific Coast palette - a nice collection of blues, greens, purples, and browns. I like blending the purples and blues, then lining the bottom of my eye with dark blue. Unfortunately, it doesn't look like this palette is available anymore, but she has some other great options on her website and Sephora.
I've been a fan of Maybelline's Great Lash mascara for quite awhile. It's dark, stays put, and doesn't clump. Right now I use the non-waterproof variety, but it doesn't smear and is still somehow easy to take off with a baby wipe. I've also used the waterproof one, which is excellent for all the same reasons.
