For eyes, I recommend either Givenchy or By Terry (the second ones are really good). There also used to be the Molton Brown lines (available online) but they discontinued it, so they're getting increasingly harder to find.
For lips, Chanel glosses are fantastic. My new favourite lipstick is Stila's Natalie, it looks so natural yet done up.
I don't use foundation or powder (the first is too heavy for me, the second is just a bother), but if I want a clean base, I'll put on by Terry's purple "base" (I can't remember the name).
Never really got into Mac, found their glosses to be fly-traps... Couldn't deal with my hair being stuck to my lips whenever the wind blows.
