Chanel Mat Lumiere and Diorskin Extreme Fit. Expensive (I usually buy off eBay or scout around online to find the best deals, we don't have a Myer/DJ's or individual stores here), but seriously worth every. red. cent.
I find it really hard to track down a foundation that has good coverage without becoming cakey (I have a big scar on my cheek that I'm self-conscious of, and my skin-tone is quite uneven), and my skin is that odd *white* tone that most foundations are far too orange or pink for. Dior has an amazing range of shades for Cullen-esques like me so I figure it's well worth spending the extra cash to get something that looks really, really good rather than saving a few bucks and getting something pretty average.
I'm a SAHM so I don't get to crack them out very often, for day-to-day wear I use L'Oreal Infallible (mixed with an Avon foundation to stop the cakeyness, especially during summer, and get the colour just perfect) and finish with L'Oreal True Match powder (which I also use with the more expensive foundations, it's really nice).
