Teens wearing makeup

Hi ladies,

So my 14 year old daughter has been asking me for makeup every where we go-the mall, CVS, the grocery store and I keep saying no or wait until your older but she keeps asking and I’m thinking of just letting her get some. What do you ladies think? I’m not exactly sure what she wants to wear so should I have a talk with her first? Or just tell her what I’ll allow her to wear? She’s my oldest so this is all new to me. Sorry!
