Leggings, Tunics,and Boots...Oh My!

As I've started visualizing my fall wardrobe, I have visions of this...

Or this:

Or maybe even this:

Notice a common trend?  I am totally obsessed with this look and have compiled the following shopping list.

1.  Flats---preferably leopard-print

2.  Boots---these are Frye, which I am totally loving, but I doubt my husband would love the $300+ price tag (!)...anybody have a recommendation for a good knock off?

3.  Some cute scarves

And then lots and lots of tunics/oversized shirts and leggings.  But here's where I get a little confused...are those leggings?  Or are they skinny jeans?  Either way, does anyone have a good pair to recommend because whenever I try these things on, it doesn't seem to accurately get the look.  

Anybody else digging this look too?  Or any other Fall necessities I should add to my list?
