Foley + Corinna's City Tote has become a modern classic. I still hope to own the real deal someday! The one shown here goes for $485 at Bloomingdales.
If you love the look but can't spring for the real deal, Forever 21 has a similar looking bag called the Genevieve Faux Leather Tote in blue or black for $32.80. I bet this beauty will go fast.
