Of course MAC (which is very pricey over here in Australia compared to the US) for eyeliners, shadows, lipsticks, etc etc... Fav Brand. but...
For foundation: Lovvve and will always love Revlon Colorstay (now its Colorstay Active since my skin has cleared up heaps, but used to be Colorstay Natural).. it just really stays put, and so cheap.
For bronze/blush: Benefit... haven't tried any of the shadows but i love love love Hoola, i don't go a day without wearing it (but the brush it comes with is absolute crap).. its the perfect colour to match up my face with the rest of my body (in terms of tan lol) and no shimmer whatsoever, which is good for everyday. And u have to admit, the packaging is just gorgeous!
For lipgloss: MAC lipglasses of course but BonneBelle is my never-fail - my HG nude lipgloss has been LipLites Cappucino for yeaaars now, its SO cheap, perfect pinky-beige and smells so yum
For mascara: I swear by Maybelline waterproof mascaras. Seriously waterproof, only mascaras ive found to hold my curl and right now loving Turbo Boost.. makes lashes look so thick!
