I have... 4 different colours. Hot Tahiti, VG Gaga, VG Gaga 2, and Baron's Rose (I think? Whichever one came out with the Tartan Tale bag.)
I really don't wear a lot of lip product. Somehow I'm perfectly fine with having a million colours on my eyes, full contouring, etc. but putting lip product on feels too done. Even with a neutral eye. I am trying to get over this phobia, but I don't know how. I pretty much wear VG Gaga 2 all the time because it's the perfect nude for me. (Seriously, even the MUA was surprised. I really only tried it on for a lark because I adore Lady Gaga. Neither of us expected it to work.)
Ironically, it used to be I would not leave the house without foundation, mascara, and Hot Tahiti on... And now all my lovely l/s, l/g, and kissable lipcolours are sitting unused.
