What are some fashion trends and/or items, that make you think: 'Why is this a thing? Who thought about it? I am glad they did though!'?

This can be either something you like to wear yourself or something you like on others. It has to be something that you wonder, how people thought about making it a thing, but you are glad that they did. You can have a theory of why and how. If you have a theory please share it I am especially interested in those.
Also it may be something others may think is completely normal. This is a subjective question.

For me it's hoodie dresses. Whoever thought about making 'We like to wear guys hoodies anyway, so lets make it more feminine and a near complete outfit. ' something that exists: Thank you!!
They are casual yes, but if you want casual they are great. I am not saying we can't wear normal hoodies, but let's be real, if I want a normal hoodie I just get one of his.

I am not asking about trends or fashion items you just think are weird. I am asking about those you like or wear.
