Don't get me wrong... I love MAC. But their lipsticks are rather hit and miss. There are the classics; you can find them on the Back 2 MAC lists or countless blogs. The staple lippies wont let you down but buyer beware for limited edition shades or more tricky formulas. Some can glide on with full coverage with barely a swipe and other drag like sand paper across your gob.
The great thing about MAC, and especially their lipstick, is the variety; both in culture and texture. It's so much more than just the run of the mill 5 different pink selections you find in other ranges. If you are looking for a shade that is a little out of the ordinary (or completely?) then MAC would be the way to go.
All MAC lipsticks have a vanilla scent that some people don't mind and others hate. It is nowhere near as strong as some other brands (I'm looking at you Revlon) but still detectable.
I love MAC its the only lipsticks I wear for the following reasons: They smell amazing, all the lipsticks have an amazing vanilla smell that doesn't leave no matter how long you've had the lippy for. They come in amazing colours! I have 10 different ones at the moment. I often find that Ive taken my lippy off with make up wipes and there is still a stain on my lips in the morning so they sit quite strongly.
Tips: Make sure you go on pay day to get some because they are so addictive!!
Also keep all your empties (anything in a plastic case eg. powders too) because when you get to 6 return them and you get to choose a lipstick for free (:
