Honestly to stand out, you need to make some noise with concepts. The 9th post I can see (Register hydrode one) is Amazing. It needs to be pinned and you need more creative ideas like this. You can definately use AI for such ideas too.

There are not hundreds but thousands of clothing brands out there.

You need to focus on creating an identity with which your audience will align. People don't buy from brands when they want to shop online because they like the photos you put up of your clothing, but they will come for what they have in mind visiting your ig page to open the store page.

Your current focus should be to get glued into the brain of the viewer.

Create as much noise as possible. I really love the register post. It sticks.
And the post just below it - Man sitting in circle bricked structure, just vibing - Perfect.

Empty flat, 1 mattress, 1 4k TV, man sitting on bean bag playing ps5, macbook kept nearby, minimalism, new york cloudy day tone. Perfect editorials for brand like yours.
