My Audrey Pants

Yesterday I finally purchased my own pair of black "Audrey" pants. You know what I'm talking about. They are tight, black pants that are cropped at the ankle. Audrey Hepburn wore a pair like this in Funny Face, hence the nickname. I am struggling with what kind of shoes I should wear with these pants. The below picture (courtesy of bcbg.com) shows the pants wore with booties, but I think flats look better. What do you think? And are there any other shoes that would look good with these amazing pants?? Help!
