Thanks for the insights, everyone!
I agree that a longer cardi might have worked here. I started with one in green, but swapped it out because it didn't go with the shirt (which is lavender). I like longer cardis, but tend to stay away from the "boyfriend" styles, as they end at the widest part of my hips, or get hung up on my substantial booty.
The pants are perhaps a little snug. they have loosened up as the day goes on (as pants tend to do). I'm not convinced about these yet.
Interesting thought that the shoes are too clunky for the pants. I hadn't considered that. I'm starting to wonder if my shoe closet needs more work.
A jacket might be a good idea, but it might make the whole look too formal for work. (would it?) I'm a PhD student in the sciences, and I don't teach--jeans and tees are expected, and there's a decent chance on any given day I need to hop in the lab. Then again, that's why man created lab coats.
As far as style direction goes, I'd like to move to something that's funky fun/eclectic (hence the shoes), and feminine, with a possible dose of retro inspiration, as I can sport most hats with ease, and fuller skirts are good to me. And a good dose of global traveler (because I am one) This look is too classic for me, and when left to my own devices, I have a bad habit of falling into jeans ruts.
