for those who have gotten it in past couture collections, what is the coverage like? is it comparable to MAC studio fix powder? or less coverage? also is the finish pretty matte or more natural? i really want it if it has decent coverage because i'll get 2 powders for $50, almost the same as studio fix powder, but with the added bonus of pretty packaging! lol. oh yeah, and what would an nc37-40 get? the medium one? thanks!
