Using two different template styles

-- url of the page with the problem -- : www.modelmisconduct.com/shop/store
-- Joomla version -- : 3.4.1
-- PHP version -- : 5.4.13

I am using two different templates

1) for main site
2) for store

How do I assign Hikashop to use a specific template style for Store, Category Listing, and Product?

Situation A:
www.modelmisconduct.com/shop/store/ use template 2. However, when I click on a category ( www.modelmisconduct.com/shop/store/clubwear/dresses ), it uses template 1. How can I keep it using template 2? for the category, but then switch to template 1 for the product view?

Situation B:
I display products on a landing page ( www.modelmisconduct.com/shop )on template 1. When the user clicks on a category from the (category module mid page), I would like it to use template 2.

I understand that normally. But it isn't working as that now.

If I assign a specific template to a menu that has hikashop assigned to it template 1 comes up, but when I then click on a product, it changes templates.
