It's a pretty bulky skirt, so pairing with a slim fit top is really the only way. You've already done that, so except for different colors, that's about all you can do. I like this top, though.
I have something like that! A solid colored, loose off the shoulder or tshirt, tuck it into the skirt and pull it out a little bit :) or a tight tank or a button up tee, both tucked in.
