Done in royal-blue cotton corduroy, this bold take on the trench is unlike anything else in your closet. The long silhouette is fitted, and it has sharp notched lapels, buckle cuffs, and a belt strap that loops through the storm flap and buckles high on the ribcage—a unique detail that’s quintessentially Rosie. Wear it open, fasten the hidden button, or cinch it up—it works every way.
