There's an YSL Rouge Pur Couture lipstick that's very close. Less of a matte finish, but the colour is the same. I believe it's No. 27- it came out with their Fall collection, but the colour is permanent. I believe someone (sorry, not sure who) said that there's a shade from Stila that's very similar as well. And, of course, when Mac has a successful colour, they do tend to repromote it.
I'm really eager to see swatches from this collection, not that we're likely to for a while. The shades we've seen already look so pretty! And, of course, this collection has the HerGreyness stamp of approval, which is much desired...
