Her Lorde look was all about having a distinctive performance persona "with a bit of drama" she told the Herald. "I'm not promising perfect skin."
The collection's eyeliner and lipstick were part of her own identity and it was "cool" that friends and fans could buy into that.
In New Zealand, that won't be until late June.
"I'd like to think my products are about highlighting aspects of your face that you really like and you want to accentuate, because that is what I do because I am not so confident about my skin," Lorde said.
M.A.C creative director James Gager said Lorde was a trend-setting artist. "She certainly isn't afraid of showing her unique sense of style both in her appearance as well as her performances, and we truly admire as a brand anyone that has great sense of style and isn't afraid to be who they are."
Lorde knows she is putting herself out there for renewed scrutiny with the collaboration, but she is happy to own her appearance, flaws and all. As to where that signature dark lip comes from, she laughingly explained to international media: "New Zealanders like black."
