Also, if there is an aesthetic already like this, PLEASE tag me!

If this is real, add youtube kids as a subgenre. It's in a Waaaaay different ballpark than kidcore. It's like kidcore, but mixed with weirdcore and a dash of corporate.

Seems a bit too broad?

Ok so, this wouldnt be able to be an aesthetic becuase its defined by a non visual theme, there are youtubers for every aesthetic and merch that spans a very wide range as well.

A fashion blogger wouldnt be anywhere near the same aesthetic as, idk, a gaming channel.
