When did Halloween go from being about scary costumes to just being about... costumes? Well let's not worry our fake blood-encrusted little heads about that just now. Instead let's thank Idolator for compiling a handy countdown of the worst music-related costumes available this Halloween.

That's right, if you feel the need to hide the fact you have zero personality this coming Friday, and wish to highlight the fact that you also have zero imagination, there are plenty of ready-made options out there for you to consider. Although I'd say that as these costumes are in that big old store known as "the internet", you might be a bit late ordering them for this year.

You might think this outfit above is Madonna (click image to enlarge), but I'm guessing image rights came into play somewhere between manufacture and retail because it's actually entitled, rather lazily, "80s Pop Star". But at least the model is posing with the microphone pointed directly at her eyes, just like they did back then.
