Why the main page helps first
It gives you a quick overview and lowers the chance of choosing the wrong section too early.
Decision page
The simplest starting point is best when you are new.
If you are new, start with the main page once, understand the layout, then move into a category page when the choice is clearer.
Start with the clearest first step, not the biggest menu.
Why categories help second
Pages like shoes, bags and jackets are easier once the choice is clearer.
Best next click
If you still are not sure, use the main page. If you already know the lane, use the categories page.
