Our girls have at least 8 different dress-ups between them. Char has one cape that fits and one of those plastic red fire hats the fire departments give away for free. It's being held together in several spots with tape. That's it. That's all he's got. Not even one, all pieced together, costume. And the girls want to play dress up all the time and many times argue that he can't play unless he's dressed up as something.
While at Costco this weekend, I noticed they had several boy costumes out and I found the perfect one for Charlie. I brought it home, he tried it on and has worn it(or at least a part of it) every day since. We call him the 'defender of the princesses'-as we have three of them- and the 'dragon slayer', since he's not allowed to kill people, only dragons. This prevents him from hitting his sisters....though I'm sure one day he'll just ask them to pretend to be dragons and then we'll have to think of something else.
