We put things in them. They keep our hands warm. They're conspicuous in their absence on pants, and a pleasure when included in skirts.
Quite a lot of women's pants patterns, and most skirt patterns, do not include pockets. What a shame, and how annoying, we say, but luckily, pockets are easy to add!
There are many different kinds of pockets, so it's important to choose the right kind for your project. For example, on pants that fit slim or tight through the hips, you want to avoid an in-seam pocket, which will pull open, and go for a shaped pocket, which will stay flat across the front.
Here's how to add a shaped pocket:

|Left to right - the pants leg with the pocket shape cut out; the pocket facing; the pocket bag "fill in"|
|Here's the back (inside) of the pants leg - the pocket facing and pocket bag are stitched together around the bottom.|
Once you get the hang of it, you'll be cutting pockets into everything!
