Beyond Sizing Up: The Construction Problem
For years, the standard advice for anyone with a broader frame has been to simply buy a larger size. This is a flawed approach that swaps one fit problem for another. A coat that’s wide enough in the shoulders often becomes a shapeless tent around the torso,
with sleeves that hang past your knuckles. The real issue isn’t your body; it’s the construction of the garment. Standard-fit jackets are built for a specific, narrow set of proportions. When you have broad shoulders, whether from genetics or time in the gym, you're fighting against seams and patterns that weren’t designed for you. The good news is that certain design features—often hidden in plain sight—can provide the room and flexibility you need without forcing you into an oversized, unflattering coat.
The Action Back: Built for Movement
One of the most effective but overlooked details is the “action back,” also known as a bi-swing back. This feature consists of pleats or gussets built into the back of the jacket, just behind the shoulders. While the jacket is at rest, these pleats lie flat and are often nearly invisible. But when you reach forward or lift your arms, they expand, giving you a crucial few inches of extra material right where you need it. This completely eliminates that familiar, restrictive pull across the upper back. Historically found in sportswear for hunting and motoring, the action back is a hallmark of functional design that has made its way into modern field jackets, moto jackets, and even some tailored coats. When shopping, it’s a detail worth seeking out for unparalleled comfort and range of motion.
Gussets: The Diamond in the Rough
A close cousin to the action back is the gusset. A gusset is a small, often diamond-shaped piece of fabric sewn into a seam to add breadth and reduce stress. In outerwear, you'll most often find them at the underarm. An underarm gusset provides a remarkable increase in your arm's range of motion, allowing you to lift your arms without the entire body of the jacket riding up with them. Some jackets even feature shoulder gussets that work in tandem with an action back for maximum mobility. While many jackets have them, they are rarely mentioned in product descriptions. You often have to physically inspect the jacket's construction to find this hidden gem, but the improved fit is well worth the search.
The Power of the Raglan Sleeve
The type of sleeve on a jacket can dramatically affect how it fits your shoulders. Most jackets use a “set-in” sleeve, where the shoulder seam sits directly on top of your shoulder point. For a broad-shouldered person, this seam can feel tight and restrictive. The alternative is the “raglan” sleeve. A raglan sleeve is easily identified by its diagonal seam, which runs from the underarm directly to the collar or neckline. This design eliminates the rigid shoulder seam, creating a softer, less-defined shoulder line that offers more room and flexibility. Because there's no fixed shoulder point, raglan sleeves can be more forgiving for a wider range of body types and are a fantastic choice if you find traditional jackets constantly pull at your shoulders.
Material and Other Considerations
While construction is king, the material of your outerwear also plays a crucial role. Look for fabrics with a bit of natural give, like certain wools, or modern materials that incorporate a small percentage of stretch. These fabrics work with features like action backs and gussets to enhance comfort. Additionally, look for other flattering details. Single-breasted coats create a cleaner vertical line than double-breasted styles, which can add visual width. Similarly, a coat that cinches at the waist, like a wrap coat or trench, can redefine your silhouette and create balance by drawing attention to your midsection rather than the width of your shoulders.
