Okay, look. This Bows(er)ette meme is completely wrong, and no one is talking about it.
This crown is designed to be a power-up for Toadette. It's a crown (representing Peach) with a pink mushroom cap inside (representing Toadette), and when worn, it shapeshifts the wearer into a Peach-like girl with Toadette's pigtails and a pink mushroom-print dress. The new character is called Peachette (Peach + the '-ette' suffix from Toadette).
At best, this same power-up should turn Bowser, or anyone who wears it, into an exact copy of Peachette, i.e. Peach with pigtails and a mushroom dress. But instead, for some reason, the same power-up (a crown with a pink Toadette mushroom) turns Bowser into a Peach with a
black dress and an otherwise Bowser-like appearance, with no indication of a relation to Toadette. Notice, the name is Bows(er)ette, retaining the suffix '-ette' from Toadette.
Now, there are two ways that this can be redesigned (which it should be):
(a) Change the power-up's visual design so that it's just a special crown, and anyone who puts it on becomes a Peach version of themselves. Nintendo's failure to begin with was making it have a pink mushroom on it, which makes it a pre-destined power-up only for Toadette, not understanding that it would explode in popularity and be stepped all over as a power-up to be used by everyone.

(b) Change the power-up's design so that it always reflects the character who's using it. If Bowser is collecting the Super Crown and becoming Bows(er)ette, then the crown should have horns and red hair in the middle, or a spiky green shell.

And then, there's the issue of nomenclature. Like Peachette, the name needs to be Peach + a suffix representative of its wearer. So for Bowser, the name of this new girl should be Peacher, Peachser, Peachoopa, or anything in the same vein. I think a prefix is also acceptable, such as Bowspeach, or a name like King Peach. "Bowsette" suggests Bowser in the form of Toadette, not Bowser in the form of Peach.
