I have played with them a little. Here are some comparisons, sorry my pictures aren't great, the light seems to be fading. I am NC25 but I think my arm is a little more tan right now. Small Vanity is more unique to me, I don't have a lot of blush in that color family. It is a nice dusty rose, mugh lighter than NARS Taos. I think Easy Manner is a bit more dupeable if you have a lot of light peachy-pink blushes.

L-R/bottom to top: Tarte Exposed, Small Vanity, NARS Sin (I couldn't find any dupes in my MAC blushes)
