Ah - a topic near and dear to my heart, as you may be able to tell from my user name.
These days, I tend to wear these with skirts and dresses:

And sometimes these:

My style is shifting a bit but I still sometimes wear this:

And when I have a day where I'll be doing a lot of walking (e.g. being a tourist), I wear this (though my version of this style seems sturdier than the one pictured):

For a day where I'll be standing a lot (though not walking a lot), the regular clog-style Mary Janes are good, although heed the warnings that the strap can break off. This just happened to me as I was walking along so I'm not happy with that.
In the fall/winter, I've worn skirts with this, though I'm currently on the search for something a little edgier:

And these in fall/winter with tights or leggings (or with pants/jeans all 4 seasons. Actually, all these Danskos work well with pants/jeans too.):

Good luck in your search!
