Ever since I picked up a tube of lovelorn, I have been madly in love with it. I can't think of any MAC shades off the top of my head in l/g, but a cheap way to go that I would recommend is Loreal color juice in Grape soda... I pair these two all the time and love the look!
Cultured lipglass has that mauvey pink lilac look of Lovelorn on me. I <3 Lovelorn so much! It's so pretty. Morning Glory lustreglass is close to it too, if u want some extra sparkle.
