That sounds like a good start.
And it was just my own impression that MAC was for younger women, but I am quite fashion clueless, as evidenced by my other posts expressing major eyeglass confusion, LOL. I have good luck with some Bobbi Brown products, but they're way too expensive to buy often.
P.S. This has nothing to do with makeup, but if you get wedding pictures taken outside in warm weather, make sure you are very well-hydrated, with tons of water on hand, and drink even more than you think you need. Otherwise you could get light headed from the heat, the stress and your dress. I learned this the hard way.
