How do I get makeup out of a white silk blouse?

I put on my brand new very expensive white silk blouse for the first time this morning. I went to close the cap on my concealer and it squirted out and landed squarely on the front of the blouse. I left the shirt alone because I was running late for work and didn't know how to treat it anyway. I just want to know the best way to get the stain out - money is not an issue in this circumstance, so if the dry cleaner is my best best to get the stain out, please say so. I am just sick about it.
