I only have a couple of blushes from MAC, which is weird considering I always eye them up when I visit a counter! A few months ago I decided to get this one, Melba, which is a matte peach. At first I was a little unsure as to whether or not it would suit me, but the MUA applied it and said it looked beautiful (hook, line and sinker eh) so a couple of minutes later it was mine! I would say it's quite similar to NARS Gina but not as bright.
I'm not sure which one I would recommend really as I use both all the time, personally I prefer the packaging of NARS products but they are prone to cracking so it's up to you really. Have you tried this blush? What's your favourite MAC shade if you have one? Or your favourite blush formula - cream, gel, stain, powder.. ?
