long/short skirt

I have been on the lookout for more "office" friendly pieces lately. 

This skirt is an ideal choice for me. It is a long, polka dot skirt, with a short black skirt underneath. 

I wouldn't quite classify it as a "high low" skirt, but it is definitely not a 1990's long flowered skirt either.

love the pattern!

and the price!

I am thinking of wearing this with a white shirt, tucked in of course, and a BIG black belt. 

Ideas?
