The fat shaming in here.
The hair change was definitely a bit premature, I think. A change in sound without a change in image would have been good enough. Any recognisability she gained during the Title era is completely gone. At least it's just hair and she can change it back if she wants, but I think a hair change would have been better saved for a third era (i.e. Rihanna during GGGB with the short hair, Ariana during Focus with the silver hair).
