This makes me crazy!

My daughter, she's 12, wants to be Joan of Arc for Halloween this year. This part, I love. She recently studied Joan of Arc at school and independently picked this as her costume choice. Now, my daughter is tall for 12 and has a developing body. She looks like a teenager, not a child. This past weekend we started looking at costumes. The picture below is representative of what we found.

Can I just say, WTF? Why are all women's costumes "sexy" something or other? Needless to say, we were horrified and went to the fabric store and I'll be making her something. But, if we wonder why girls don't appreciate their worth or feel inferior, look no farther!
