What is a good colored shirt for my daughters purple skirt?

I just bought my daughter a dark purple skirt and haven’t been able to figure out a good shirt to go. What would go best, color-wise, with a dark purple skirt.
She’s 6 years old..btw

Accord to color wheel theory (colors combine harmoniously on opposite sides of the wheel) http://www.color-wheel-pro.com/color-theory-basics.html
