Amal Clooney steps out in gorgeous and enviable designer duds from head to toe heading to teach at Columbia University where she is a Professor of Law. I don't know about you, but none of my professors ever dressed this fabulous! The human rights lawyer wore a trench coat by Proenza Schouler, which rings in at a whopping $2,750, but you can make this staple piece a part of your wardrobe for much less. We love how "fall" this dressy look is with a bright purple hue that isn't typically associated with this season, with clean and classic black accessories - we give this outfit an A+!
