Button Your Cardigan Right to Avoid a Bulky, Bunched Look

Start With the Right Cardigan Fit

Think of your cardigan as a suit jacket. If it’s too big, you’re sunk before you start. A client showed up last fall in a beautiful cashmere piece, but it was two sizes too large. In every test shot, the fabric pooled around his waist, making him look ten pounds heavier and completely shapeless. We had to ditch it. The right fit skims your body, never pulls tight or hangs loose. You should be able to comfortably slide a flat hand between the knit and your chest. Check the shoulder seam: it must land exactly where your shoulder bone ends, not an inch down your arm. Sleeve length is critical—it should hit right at the base of your thumb, allowing a quarter-inch of your shirt cuff to show. Get this wrong, and no button strategy will save you.

What’s the most common fit error I see? People buy a cardigan to feel cozy, so they size up. For portraits, that’s a visual disaster. Cozy reads as sloppy on camera. You need the structured coziness of a correct size. A medium-weight cotton or merino wool knit in your true size will always photograph better than an oversized chunky cable knit.

The One-Button Rule for Seated Comfort

You will be sitting for most of your session. Stand in front of your mirror right now and sit down in your cardigan, buttoned as you normally would. What happened? I’ve watched a hundred people do this. The fabric immediately pulls across the chest and back, creating horizontal strain lines. The bottom hem rides up. The whole garment shifts into an awkward, tense position. The solution is simple: fasten only one button. Which one? The one that sits closest to your natural waist, usually the second or third from the bottom. This single point of closure anchors the cardigan to your torso, letting the rest of the fabric drape naturally as you move and sit. It prevents the dreaded “bunch and bloat” around your midsection.

Try it. Button that one waist-level button and move your shoulders. See how the collar stays open and relaxed? Now sit. The difference is immediate—no pulling, no riding up. This single act does 80% of the work for a sharp, comfortable look.

Adjust Your Collar and Shoulder Line

After you’ve fixed that one button, stand up straight. Use both hands to gently pull the cardigan back from your shoulders, as if you were smoothing a blazer. This simple motion does two vital things. First, it clears the collar of your shirt or blouse underneath, ensuring a clean, crisp line instead of a buried, wrinkled mess. Second, it pulls any excess fabric toward your back, sharpening your shoulder line and eliminating droop. I always do this for my clients right before we start. I’ll say, “Hold still a sec,” and give a light tug backward on each shoulder. The camera sees the instant improvement in posture and structure.

Don’t forget the neckline. If you’re wearing a collared shirt, make sure the cardigan isn’t mashing the collar points down. They should peek out just beyond the knit, lying flat. For a crewneck tee underneath, ensure the cardigan’s V isn’t sitting crooked, exposing too much of one shoulder.

The Common Mistake: Buttoning All the Way Up

This is the cardinal sin. Buttoning every single button, especially the top one, turns your soft layer into a restrictive, boxy sweater. It closes off the neckline, making your head look disconnected from your body. It creates a straight vertical line that does nothing for your shape. Most damagingly, it forces the fabric to wrinkle and buckle horizontally across your chest and stomach with every slight movement. I once photographed a brilliant engineer who insisted on buttoning his cardigan all the way. Every shot looked like he was being gently strangled by wool. We took a break, unbuttoned everything except the second button, and the entire session changed. He looked approachable, confident, and at ease.

Why do people do this? They think it looks neater. On camera, it looks stiff and insecure. Leave the top two, often three, buttons open. This creates a flattering V-shape that frames your face and leads the viewer’s eye to your expression, which is the whole point.

Your Final Check in the Mirror Before Shooting

Don’t just glance. Do a head-to-toe audit. Start high: is your collar clean and symmetrical? Move down: are your shoulder seams sitting right? Is that one key button fastened? Now look at the drape. Is the fabric hanging straight, or is it caught on your belt or chair? Turn to the side. Does the back lie flat, or is it billowing out? Finally, move. Sit, stand, cross your legs, uncross them. Does the cardigan settle back into place, or does it get stuck in a weird bunch? The mirror test with movement is non-negotiable.

One last pro tip: watch for sleeve crawl. When you bend your arm, does the sleeve retreat halfway to your elbow? If so, gently pull it down at the wrist and give the shoulder a slight tug back again. This maintains the intended proportion.

Your clothing should be a quiet frame, not the main event. A properly buttoned cardigan does exactly that—it adds texture and intelligence to your portrait without shouting. It says you considered the details. So, fasten that one button, pull the shoulders back, and forget about it. Then we can focus on what really matters: the person wearing it.
