I bought MAC Bust Out! From a CCO in York about a year ago. It's one of those lipsticks that I pull out from the depths of my lipstick drawer, draw a heart on the back of my hand and then decide to go with Rebel instead.
I love the special limited edition packaging, the Hawaiian style really suits the theme and I think its one of the better special packaging styles that MAC have done.
Bust Out! Looks quite intimidating in the bullet, it's a very purple kind of purple, if you know what I mean. But when you apply it, it turns out to be quite light and wearable, it sheers out a little into something that's actually really pretty. Think a less sickly version of RiRi Boy, in a much more lip-friendly finish. I'm not normally one to go for Lustre finishes, but I think with this shade of lipstick it really suits it and makes it comfortable on the lips.
Whenever I actually try it on my face I always think "Why don't I wear this more often?" It's unusual enough to be interesting but not so out there that I feel self-conscious. Maybe I don't wear it that often because I'm very aware I won't be able to get my paws on another one! I really can't handle another RiRi Heaux drama.
