Halloween [1] gives us all permission to dress up without feeling like an overgrown child, but some of those ghoulish fancy dress outfits either put a major strain on our bank balance or our time. The simple and cheap option is to buy a costume online that'll let you dress to impress without needing to spend an excessive amount of cash or hours painstakingly stitching your own. These Halloween costumes are so affordable you won't think twice about buying instead of hiring this year.
Say goodbye to fancy dress hire headaches and take a look at our pick of the best outfits to buy online right here, and then plan your finishing touches — requiring minimum effort for maximum effect — with our roundup of easy DIY Halloween nail art [2] and simple Halloween makeup looks [3].
