My everyday makeup (foundation--I assume that's what you are talking about) is Prescriptives. It matches me the best. For summer, I wear mostly Laura Mercier Tinted Moisturizer in the oilfree formula. I am going to try Revlon color stay active makeup because they say it's sweatproof.
Everything else.....I'm really partial to Bobbi Brown eyshadows because they don't crease on me, but I wear everything from MAC to Revlon to Wet n' Wild......anything goes for me.

I've worn Cover Girl for years - have been using the Aqua Smooth for about 2-3 years now because it gives more coverage. It holds up in the heat pretty well, but I don't know how it would hold up to dancing outside in 99deg heat with mega-sweat.

Other than that, I also run the gamut from MAC to Wet-n-Wild.

Lauren Hutton has a line of makeup especially designed for mature women. I have the Face Disk. It is the best makeup I've ever used as of yet. It gives you a smooth, flawless look without the appearance of having any makeup on .. It actually makes you look younger! You can take a look at it here: www.interwood.com/a/p/LHsite/home.shtml

I also like to use Bare Essentuals. This makeup does some pretty spectacular things for your complexion - again, without looking like you have makeup on.

Both these products are perfect for older women, but younger women also benefit from the clever technology that goes into creating these products. No, they're not cheap but I found them to be reasonable for what your getting. And as a professional entertainer, I find these products are something I cannot do without.

For everyday and work wear, I use Benefit concealor, Stilla foundation, Stilla Convertible Color creme blush, Stilla compact powder, and Benefit Bad Gal mascara. When I need more coverage I use MAC. I also have two really great powder blushes - NARS Sin and Orgasm. I like them because they are pretty sheer and they have a nice shimmer to them. I'm all about deflecting the light away from my face!
