While some are quite elaborate and traditional, there are also many Halloween costumes that are very unique. One of the best ideas for Halloween costumes, especially for couples, is to choose complementary or coordinated costumes with your partner. Some great ideas include going as pirates, batman and catwoman, Princess Leah and Han Solo, a flapper girl and her gangster beau, or even Hugh Hefner and a playboy bunny. Because the possibilities are endless, couples of every age will find matching costumes that are best suited for them. Even for couples with differing preferences, there are hundreds of choices to find one upon which a compromise can be reached. Today, more couples are choosing to coordinate their Halloween costumes, prompting many online retailers to offer more of this variety.
