Me being the rebellious child that I was, at least when it comes to make-up, I might not be the best person to answer, but here goes. Although the story has nothing to do with make-up, it is related in regards to parents.
When I was a little girl, probably around 8 or 9, I ended up playing my parents off of each other, over going to swim to a friends house. I had asked my mom if I could go swimming, and she said no. She had left the house to do some errands, so of course, sneaky little me went to ask my dad. He asked what my mom had said, and of course I lied and said yes. So he let me. Long story short, I was quickly caught in my lie and punished. (Can't remember if it was a spanking or being grounded.)
So my suggestion is, if one parent says no, then that's the end of the story. Don't do it. You'll basically be playing each parent off of the other, and that's not honoring them. What you might consider doing, in a very respectful manner is ask the one who said no, if they would explain to you why they wish you would not wear make-up right now. Your parent probably has a very reasonable answer.
