If we had a dollar for every time the Middleton sisters attended a charity event…we'd give it all to charity of course!
The 28-year-old author looked cozy-chic in a faux fur jacket, navy mini skirt, black tights, and black booties.
Though she's not as flawless as our beloved Duchess of Cambridge, we give her an A for effort for this look.
