At what age should you let your daughter wear makeup?

I started wearing makeup pretty young, around 8 years because I was involved in activities like dance and drama. If it were my daughter, when she's curious and want to try, I'd let her try gradually -- maybe start with clear lipgloss and for special occasions like holidays or birthdays if she wants. These days, there are plenty of child friendly make up meant for kids, so I reckon I'd let her experiment with makeup 8 years onwards.
