As you can tell by now, I like shimmer shades! I'm an NC 37 in MAC Pro Longwear SPF 10 Foundation with warm-neutral undertones and with my rabbit brown eyes, I think it just looks good one me (of course this is MY opinion, you may think differently and I don't mind hearing back.) Now of course, with age, we're supposed to lessen the use of frost, shimmer and the like, but I believe it depends on your technique, lid type and the product. I tend not to use frost and if I want some sparkle, I prefer shimmer, satin, or fine glitter. Here are a few good references on eye shapes and eyeshadow textures, which are important (as they may help you go a long way with improving eye design techniques.)

I once went to a B.B. King concert, not because I'd ever owned a single song of his or had any familiarity with his music or his genre, but because I knew he was the best at what he did. In that same vein, I've always wanted to experience Burning Man, not because I care about hippies, techno music, drugs, or art, but because it's the biggest and best event of its kind in the world.
For years I intended to go to Burning Man, but the problem is that Burning Man requires a huge degree of preparation. As I found out firsthand, it's located in one of the least hospitable areas of the United States, which means that you need more stuff than you're used to needing (goggles, water, etc.), and you must provide it all yourself. So each year passed by with my intentions dissolving into the reality of a fast approaching deadline and not having prepared at all. But this year was different. A friend of mine took the initiative to rent a huge RV, recruit a Burning Man veteran to come with us, and generally organize the trip.
"Well," I thought, "it's never going to be easier than this. I may as well go."
