Trick or Treat? Girls halloween costumes vs. Boys Halloween Costumes

I was at the mall today and while at Winners, noticed two racks of children's Halloween costumes. Though one could argue that children could choose from either rack, they were fairly obviously divided between boys costumes and girl costumes.

Boys could be soldiers, firemen, astronauts or bikers. Girls could be princesses, or fairy princesses or characters from fairy tales.

Children should be able to use their imaginations and be whatever they want to be. Girls should be given more choices then pretty, cute or beautiful and boys should have more choices then macho, strong or tough.
