I normally mix my foundation to best match my skin because my skin color chages too often. Mixing foundation can be hard at first but once you get the hang of it the pay is really great...you always have the correct color.
I used mac's studio fix fluid in NC40 and NC50 and im about an NC 42 now and im pretty sure that i will get more darker since it is summer and i often take my son to the pool.
the brush i used is mac190
coastal scents powder brush
mac select cover up, select sheer pressed powder nc40
