Meghan wore a beautiful ($582) coat from Line The Label. It's already so popular that their website crashed.
Not ready to shell out that kind of money but you still want to get Meghan's classic look? River Island’s cream faux fur collar belted robe coat, £90 (or approximately $120), looks similar to Meghan’s once you remove the detachable fur collar. And it's available in sizes 6-18.
