This is what Pingu has problem with , I do too. I buy matching stuff for my daughter, I buy the clothes, shoes , purses etc as per her liking. But high heels , makeup , heavy jewerly , uncontrolled piercing at this tender age is little too much I would not allow that.
Thats what I do with my kids too I let them wear matchings but not jewelery,make-up,high heels.I usually buy them pink things or Barbie things.
