A niche for instagram

So there are so many niches, like cloth, sports, luxury and stuff but I can't decide which one to chose.
The problem is that I got to steal content from other people, and I don't like it because Its never up to me. I depend on other accounts. Any of you got an idea for a niche for me? I won't upload pictures of myself with deferent cloths every time lol
If there's a thread for something like that I'm already sorry but I cound't find something similiar.

You don't have to steal. free pics also available.

Or go out with a camera and shoot nature pics all day

My advice, pick a niche that is centered around a product. So fashion is good, lingerie is good, shoes, watches, things like that. Content is often a lot easier to find, and it'd going to be a lot easier to monetize.

Pick a niche with your interest, that way you are better at picking the best content

depending on niche tell people they can sent in THEIR photos for a chance at a feature, thats what i do works very well and you have permission (hell they ask you too) to use their photos. everybody happy.

Luxury and clothes are good stuff to start but you must research your own.
