A character is marked as "badass" by wearing a trenchcoat. A Longcoat is the ideal action-hero garment, more practical than a cape but infinitely cooler than a sport coat or no coat. Also, a Longcoat of any level of "billowy-ness" makes an ideal cover for producing any number of weapons, tools, supplies, and whatnot. Certain styles of Longcoat are deliberately designed to distort the wearer's frame, making their wearer's access to Hammerspace almost believable to mundane eyes.
