When it comes to Halloween costumes for boys this year, the bloodier, the better. Tom McDermott of Fairfield's Party City says he's seeing a lot of boys going for grim reapers and monsters costumes. Other popular costumes, he says, are Star Wars and Superman costumes.For girls, he says feminine costumes such as angels and princesses are what's in. Teenage girls, though, are bit more daring according to McDermott. He says parents with two or more kids won't have to worry about spending a lot of money on costumes. He says parents can buy costumers for two children for about $50. His best advice is to know what your budget is before shopping.
