A few years back, we had a children's Halloween party at church. We thought it would be fun to let the kids dress up in funny costumes. We don't get much chance of doing that around here in Malaysia. Anyway, I made a cape for my girl and she became Little Red Riding Hood. That cape is still around, though heavily abused. It's been used for all sorts of things according to their imagination -- blanket, superhero cape, carpet etc....
My boy was lucky to be loaned a tiger suit. He didn't like to wear the head-part of the suit. But he looked real stripey cute.
Anyway, my point is children like to dress up. It fuels their imagination. Some people have a whole chest of old clothes to play dress up. And if you don't want to end up like me, sewing disasters instead of wearable costumes, you could look out for costume sales.
Apart from Halloween, when would you wear funny Halloween costumes? How about having a costumed theme birthday party? Ooooh, I'm sure all the little girls would want to dress up as a princess or an angel. And the boys can be a fire fighter or a Harry Potter.

They also have costumes for adults. Hehehe. Imagine dad in a spiderman's costume. You don't have to buy the costumes, you can rent them for such special occasions.
Well, next time you're thinking of a party, consider having a costume party.
