The most important thing is to wear as much makeup as you really really feel good with and think yourself beautiful with.
However, answering the question directly, I'm often put off by too much makeup, I know a lot of women who look really beautiful with minimal or no makeup at all and I like it the most; but there are other women who look really great even in a bit stronger/heavier makeup :) The important things is consciousness of your own beauty and using makeup as an (optional, really!) tool to bring it out a bit more, without falling into a trap of overdoing it :)
