If I am only going to buy ONE, which one should it be.Generally I wear a lot of browns, golds, purples, and dark greens with black liner and white(ish) on the brow bone and tear duct.
Regular = matteSin = nude shimmerYou could wear Sin by itself, and you can transform any blah matte eyeshadow, since the shimmer blends in.If matte's your thing, go for the regular.Over and out.
