As far as we're concerned, on the list of Important Relationship Milestones, dressing up together for Halloween is way, way up there. How can you, in good faith, introduce your parents to somebody who hasn't even proven their support for your devoutness to Justin and Britney? It just wouldn't be right. So, whether you're in a long-term relationship or just getting comfy with someone new, this Halloween is the perfect moment to try out a couples costume. It doesn't have to be weird, or awkward — just awesome.
What's that? You're single? No problem. Any and all of these costumes could work for friends, or even a threesome. Better yet, most of these outfits are timelessly cool enough to to double-duty as Halloween fare and regular wardrobe investments.
