Nicki needs to keep this hairstyle as her "main" style for at least 3 years.
It'd be nice to see her crazy fashion style toned down a bit. She always looks amazing when she's not dressing up, and the public doesn't eat her up, too.
She needs to do a dark theme and keep the black bob and the silver/blonde wig she wore in the MDNA tour video clip. Just my opinion but she should keep it minimal and simple it looks the best.
