I've just been playing around on T's swatch comparison tool, seeing how close some of the shades are to ones I already have. I'm actually kind of surprised that many of the Audacious lipsticks are more original than I'd believed. I think the reds might be easier to dupe, which reds almost always are, but the other shades are quite unique.
Preliminary list, further investigation pending:
Greta
Angela or Silvia (I've been looking for something fairly bright and right on the border of purple and pink)
Fanny (I feel like I MUST have a dupe for this, but I can't find one)
Charlotte
Bette (again, shocked I can't find a dupe for this among all my burgundies)
Vivien (Thought this would be a dupe for Givenchy Framboise Velours. It isn't and now I want both.)
Liv
Ones that I want, but I feel like I have a dupe for already:
Ingrid (Looks like Armani 611)
Dominique (looks like the LE Mac shade Blooming Lovely)
Marlene (I think this is going to look like Hourglass Raven or Guerlain Gardner, or the two of them mixed)
Anna (Incredibly beautiful, but I have Mac Mehr, which I think is similar- might get it anyway)
Audrey (think it might dupe Urban Decay Manic)
Vera (I swear I've collected a bunch of shades that look like this, mostly from Guerlain- Madame Batifole, Rouge Grénat, Gladys...)
Janet (looks like UD Jilted)
