Alongside Lady Gaga, Nicki Minaj is reportedly one of this year's most popular costume choices. It's not a shock: with her chaotic take on the "Barbie Come To Life" concept, the Pink Friday star's hyperbolic style is so grandiose that it seems Halloween was invented to accomodate its intensity. Though Minaj fluctuates looks as rapidly as her vocal stylings, it's safe to say you're going to need a pretty dramatic wig to achieve any of them; the towering blonde beehive is a safe bet. From there, you need to locate the zaniest minidress you can find, preferrably something that evokes shades of 80s Mattel. Then you need to ask yourself: "what would a Harajuku Girl do?" This Japanimation obsession, too, is core to Minaj's style mystique. You could always add a few accessories from Gwen Stefani's actual Harajuku Lovers line. From there, garish and girly makeup – Minaj's own Pink Friday MAC lipstick, perhaps – finishes off the look.
