a simple, elastic-waisted skirt takes little time at all. it still looks nice enough, though it is not the best way to make a skirt if you have time to make something else, but still works perfectly fine. all you do is use a plain rectangle of fabric, embellish it (just rows of lace work best, but bustles and such can be added later), and then add elastic to it. then you can find a ruffly victorian-looking blouse somewhere, i am sure, as peasant style is still huge and it seems to be drifting closer to victorian.
good luck. ;D
