If I'm a NW20 in MAC or a Stay Ivory 01 in Clinique's Stay True foundation, which would I be in BE? I'd love to just try it out with some samples, but everyone on ebay does it by color. Also, could anyone recommend BE blushes, etc. that would work well with my coloring? Lastly, what are the things like mineral veil, warmth, etc.? Thanks so much!
