Is her dirty wild child image as how she debuted it more reliable or can she pull off the sexy and also glamorous (at times) look much better?

she has looked so good since the Warrior era, infinitely better than that trashbag she wore.

Why not both? Some wild looks work and she looks dynamite when she's put together. A good balance never hurts. It's just when and where

Wild Kesha looks miles better, 'Sexy' Kesha is better for her image.
