There have actually been serious scientific studies done - IIRC they were in the US and the UK. Bosses would say they preferred "all natural". Then, when shown pictures of women in no makeup, "natural" makeup, professional office makeup, and night-out makeup - which women do you think they thought were more competent? The ones in make up. They even preferred the ones in more glamorous makeup over the "natural" makeup - and that was for office work...
I don't know if it's the same in the Netherlands, but...
