If you always reach for winter puffers, listen up! Kate Middleton just proved that cozy trench coats are this season's biggest trend. She joins other A-listers like Jennifer Garner and Meghan Markle who are swapping bulky parkas for sleek alternatives. While we don't know the exact price of Middleton's Catherine Walker Bespoke coat, this classy lookalike nails the aesthetic - and it's on sale for $68. Like Middleton's choice, this popular Grace Karin coat comes in a sophisticated green hue that contrasts perfectly with neutral color palettes, while also looking festive.
