Help RE: categories/sections - can I do this and how?

Ok, please bear with me as I try to explain what I would like to achieve...

I would like shoppers to be able to browse products that are for women, kids and babies... so have those three distinct sections.

But as well as that, I still would like the traditional list of categories where the products are categorised according to type such as skincare etc (and one would find skincare for women, babies and kids in that section).

I don't want to throw the "women", "kids" and "babies" sections among the general category list... I'd like it to be obvious to a shopper that they can jump straight into the womens area and see all products for women, or that they can browse by general category instead...

How can I achieve this? And what is the best way to do it...

What would you do?

Thanks so much in advance!
