I guess it boils down to personal experience, because everywhere I have gone (in terms of professional settings) people have at least been wearing minimal makeup. Hmmm. I also think it depends on the degree of the event. I don't know where you work, but I am going to be working in the corporate world; I believe that women at least wear a bit of makeup there. I think there's a difference between not having time to wear makeup everyday and refusing to wear it altogether, however.
