(CNN) -- Nothing gets people in the Halloween spirit like group costumes. Teamwork was the finishing touch of many iReporters' outfits -- whether it was a team of green Army men or crayons. Many iReporters devoted a lot of time and effort into perfecting their costumes, such as Jason Chuon and his partner Jeremy Kidd, who went to creative lengths to create their nun-chuck couples costume: "We did some searching online and came across a website that sold chain links in every size and color one could imagine." They chose a hollow chain, cut it, tied each end of the chain to thin, plastic hair bands and finished it off with metallic-looking headbands. They chose to do a couples costume after Kidd proposed to Chuon on a business trip in Hong Kong a few weeks before Halloween last year.
