Depending on the type of black and white wig, it can be used for dressing up as a vampire, a corpse bride, a “dark Alice” or dark angel, or a zombie. It could also be used for cosplay, as part of certain anime or manga costumes. In a any case, make sure the wig is of decent quality. It should not feel too itchy, the hair should not fall out easily, and you should be able to style it so that you can make it look exactly the way you want it to. Of course, if you plan on wearing the wig just one night, you should probably go for something that is not too expensive.
