Help with matching Mac Face & Body

I've heard great things about this product & am REALLY interested in buying some. However, I'm not sure which shade to get & don't want to waste money on a high end product. Right now I wear Tarte Amazonian Clay Foundation in Ivory, I feel like it matches well, but I don't like the matte powderish finish. I am on the fair side & have pink undertones. A lot of foundations turn orange within an hour or two of wear no matter what primer for setting spray I use. If anyone could help me pick a shade that would be phenomenal! Thank you! http://imgur.com/N03uHIT (This pic is the Tarte foundation mixed with Maybelline fair to medium BB cream, BC I like the finish better)
