That outfit is actually originally a GenX fashion lol. GenZ just steals all of our fashion and pretends like they made it up. Millennials did that too. We all wore biker shorts and button down large tops and large t shirts in the 80s.
I just personally think each generation should dress in what looks good for their generation. You weren’t trying to pull off baby grows and onesies at 5 years old - same rules should apply now.
