I have 22 mac lipsticks (one is a backup which is Heroine the purple one), one Revelon and 6 sleek paint pouts. I did have about 8 sleek lipsticks but i gave them to my little sister as i don't use them.
i love Mac lipsticks but I only own about 10.. I just pick them randomly to use and feel like I will never use them all up! they are all nude/pinkish colors (too afraid to go bold) so I pretty much do not even purchase any anymore
I just counted and right now I have 44, not including backups (which I only have like 3-4 of). It'll be 46 when my Nasty Gal lippies arrive. I kinda thought I had more than that. Guess I need to do more shopping!
Off the top of my heard I have 14 lipsticks (maybe a couple more I've forgotten) and only two are MAC! I tend to fall in love with certain colours and use them until they are gone rather than buying lots and lots. I have around 8 liquid lipsticks too.
