I went into MAC last year to see if I could get matched up and purchase a foundation so I could buy my shade online. However I got a new shade in this foundation ( c4.5) when I am an NC25 in the powders so it didn't help unfortunately! I couldn't match up colours..
However I find this foundation to be quite runny and also doesn't help my oily skin. I often found that it would smear off during the day. However it is very easy to blend, the bottle top isn't very user friendly though, I would buy a pump next time. For the price though I recommend looking at Revlon Foundations, as this didn't provide the coverage or look I was looking for
I've had this foundation for quite a while now, and its average coverage! I love the finish it gives though! I set my face with a maybelline fit me powder in 310, and my shade is NW25
Tips: Get a pump for you foundation bottle! so much easier! And be careful when getting your foundation matched, the lady at MAC matched me for nw20 and it was way too light, even I could tell!
