I don't know. I don't think Lorde is worthy of a MAC collection. Didn't think Azalea Banks was, either. Or the Osbournes. None of these people really have a signature style, to me. They're not iconic in any way. And in the case of Lorde, she's only been hot for a few months. Her makeup, and honestly her whole look, doesn't inspire me. She needs a new makeup artist (if she has one at all).
I feel like MAC should choose people who are really selling an image/brand. That's why people like Rihanna, Nicki, Gaga, etc. worked. Because their makeup is just a part of their whole persona ie. being a bad gal like Riri, a barbie like Nicki, or kind of a over-the-top style-chameleon like Gaga. I just don't feel like there are many artists whose makeup/style connects with their brand. Even Beyonce, for instance. She's great, but very seldom do I think her makeup looks amazing. Damn sure not innovative. That's my 2 cents lol. Whose to say I won't buy from the collection, anyway.
I've been so bored with MAC collections, lately. It seems like there haven't been many pics/swatches of the April collections coming out. And what I have seen, besides those blush ombres, has been "blah" to me. Probably better for my wallet.
