I'm in the same predicament since I cannot wear skinnies, leans or any other form of pants tucked in when I'm out at a client's location. The tights,skirts and boots combo is not warm enough for me, even if I wear a long jacket or coat. I can only do skirts and tights in the fall, pretty much. Maybe that down skirt is for me, I would totally wear that!!!
Needless to say, I have very few options left.
I commute by train everyday and walk about 5 blocks to my office. My only solution to date is to tuck the back hem inside my booties. I don't tuck the entire thing in, just the part that skims the floor. I hope it makes sense.
It's far away from fab, but you gotta do what you gotta do...
