Early career signatures/gimmicks that artists dropped later into their career?

I've been watching classic sitcom The Nanny and I noticed that in the very first episode, Fran smacks Niles on the shoulder and says "Don't start with me Niles!" This was clearly intended to be a catchphrase/running joke because she repeats the bit several times in the first season, but it's basically gone in the later episodes.

Little things like this are fairly common on long running sitcoms- characters are often given traits and setups that get retired when the writers realize they aren't working anymore. And I thought it would be interesting to explore this same pattern with musicians as well!

When an artist is just starting out, a signature look or catchphrase can really help them stand out because it gives fans something to rally around and the public something to identify them by. But once they've broken through, then they're free to expand their artistry and explore other options.

The most infamous recent example that I can think of is the iconic "Max Cut" pioneered by Ava Max. This unique asymmetrical look was allegedly created by accident when Ava rushed to save some burning cookies during a haircut, and it became an integral part of her early branding. The silhouette was used as the album art for her singles and legend has it that journalists were even sent their own Max Cut wigs by the label. Whether you liked Ava or not, you knew she had that haircut.

But come album two, Ava ditched the Max Cut in favor of a more traditional hairstyle. And the album did worse... coincidence?

This isn't solely restricted to visuals! For example, Jason Derulo was known for always sing his name at the start of his songs, but stopped for a long time until fans begged him to bring it back. Or take the Kpop group Red Velvet, who debuted with a strict split between their upbeat red side and their dramatic velvet side that has basically dissolved over the years.

So, what are some other early artist signatures or gimmicks (either musical or visual) that the artists dropped further into their careers? Was the gimmick worth it to begin with? And do you want the artist to bring it back?
