I am absolutely overwhelmed by all the responses! Thank you all! Some great feedback and suggestions here.
A couple of people asked about my coloring- Definitely cool. I have dark brown hair and pale skin with obvious pink undertones, and dark slate-blue eyes. My best colors are basically any shade/tint/tone/hue in the red-violet-blue wedge of the wheel, including blues that shade to greens but not reds that shade to orange. Greens that edge into blue are fine. Orange is my nemesis-- these kind of middling light peachy, soft coral shades are about the only 'orange' that I can do. Yellows are also tricky for me, but as long as I keep them light I'm usually okay. There is no gold or mustard or anything like that for me. I also struggle with any but the most neutral shades of medium-to-dark brown. The khaki jacket is not one that I can pull off with just anything under it. It really only works for me with those pinkish tops.

Since I have such high-contrast coloring to begin with, I actually carry off bold prints and colors quite well. I have to be careful with pastels because they will wash me out. These sherbety shades are about as light as I go.
I found some more tops to pair with the skirt as color references (most of these tops I would never wear with that skirt, and a few I actually dug out of my donate bin just to get the color sample). http://i1123.photobucket.com/a.....20tops.jpg
The suggestions for a white top with the skirt are good suggestions, but I probably won't do it. I'm still working on exactly why not, and that's an interesting question in terms of understanding my own style, but there's something that's a little too sweet about a white top with that combination of silhouette, color and pattern.
I may be warming up to the idea of the head-to-toe mint (or sea green or jade or whatever you call that color I do think there's something to the lighting about that because if I lay the skirt and sweater on the bed and just look at them, the two greens are barely a shade off but in the photos the sweater looks a good bit darker. My leading theory is that the skirt reflects the light from the flash more than the sweater does).
kkards: I have to admit it's pretty far outside my comfort zone too, but I like to get out of my comfort zone now and then. Every now and then, I even expand my comfort zone to accommodate things that I didn't really think I'd like (such as sweater dresses. If you'd told me five years ago that I would love my sweater dresses as much as I do, I'd have said you were delusional).
unfrumped: I'm not overly concerned about the skirt being versatile. To be really honest, I don't wear skirts that often. I have a section of my closet dedicated to 'silly spring dresses' that serve no practical purpose and have nothing to do with my life except that I like them. I think this skirt fits into that corner very well, and if I only pull it out once or twice a year it's okay. What I don't want to do is buy a top I don't like just because it goes with the skirt.
smittie: you actually hit on exactly one of my problems. It's definitely not summer here, but it's a very summery color, isn't it? However, the pencilness of it and the houndstooth print say fall to me, and I definitely don't have the confidence to wear the skirt with a top that doesn't hide my tummy so I'm kind of looking at layers and sweaters. So despite the summer-time color, it has to be a winter/early spring piece for me.
Lisa: I can see the softer pastels, but I know from experience that they wash me out. I can put pastels under a black blazer or even a charcoal cardigan, but I definitely need help wearing them. And the right yellow (I'm thinking a lemon chiffon kind of yellow) wouldn't suit me at all unfortunately. really unfortunate because I absolutely love yellow.
Echo: I generally agree about the khaki/camel being too 'muddy'. That is frequently my issue with that color.
Tisa: The 'white' in the skirt may be more of a cream. I think it's white, but it certainly doesn't look white next to the white cardigan. The white in the skirt compares to normal copier paper. Again, I almost think it might be something about the sheen/texture of the fabric and how it reflects the flash. The white shoes are definitely *white*. I struggle with them because of it. I have exactly one dress I wear them with.
Ginger: I adore greens as well, and I think you're right. They play so well together (and I know exactly what you mean about blues and reds. Nothing makes me cringe like seeing a tomato-red top with crimson shoes. I think blues can be coaxed together, but it has to be deliberate. They rarely just go without a little help.) I gravitate towards more bluish greens, and I've finally learned to keep away from muted shades so any shade of green I own would work well in theory. I do run into the issue of the top being darker than the bottom and so far I don't think my white cardigan solves that problem with a darker green.
The sky blue was a good call. It's a very lush combo with the white and mint. I have a sky blue sweater that needs mending and this might actually spur me to do something about it.
Thanks, everyone for your insights! I think I have a little more shopping to do this weekend
