I honestly think Nicki or probably any other artist out there is entitled to do whatever they want (dress, act, etc) -- IF their music makes up for it
Like Gaga. She pulled out the weirdest stunts during TF/TFM eras, but her music made up for it. When BTW came out and the music proved to be generate, people couldn't stand for her outrageousness anymore.
Same with Kanye, had his music not been amazing, people would not stand for his asshole ways
I'm pretty sure most people didn't mind Nicki's kooky outfits and wigs as much as when the quality of the music started meeting public disdain (SH/RH performance) I'm just saying, if you can't make crazy outfits/actions to follow with crazy good ass music, people will NAWT have it
