Not planning on getting makeup done with the group - faux pas? I'm one of three bridesmaids, and the bride is a long-time friend. She asked if I wanted to get my make-up done with the group. I said I'd rather do my own, since I have skin problems (acne) and since I feel I can do my own well enough. She said if I did it, the makeup artist would reduce the cost for the group. 

Saying no seemed to annoy the bride, who didn't really take that for an answer and said we'll talk later. Am I making a faux pas? Should I just do it?
