I saw this question posed on http://www.temptalia.com/ and adapted it into a poll.
Personally, nobody has ever told me that I wear too much make up, but at my workplace, hardly anyone puts on any decent make up. The most the others use is foundation and some lipstick, that's all.
On days when I just go to work with only a clear face, some co-workers do ask "Oh you are not wearing make up today?" (Like duh....)
