Pockets on new suits, blazers, and coats are stitched closed with temporary thread to protect the garment’s shape during shipping and to keep it looking sharp on the retail rack. Those stitches are meant to be removed before you wear the piece. It’s one of the most common sources of confusion in clothing, and plenty of people wear their jackets for years without realizing those pockets actually open.
Protecting the Garment in Transit
The most practical reason is damage prevention. From the factory floor to the warehouse to the store, a garment gets folded, hung, compressed, and jostled dozens of times. Open pocket flaps can catch on other items, get creased at odd angles, or lose their crisp lines. By closing those openings with a few loose stitches, manufacturers keep the jacket arriving in the condition they intended: flat, symmetrical, and unwrinkled.
This matters even more for structured garments like blazers and overcoats, where the pocket sits along a carefully shaped panel. A pocket flap that gets bent or rumpled in a shipping box can leave a permanent crease in the fabric. The temporary stitch eliminates that risk entirely.
Preserving the Silhouette on the Rack
Clothing designers spend considerable effort getting a jacket’s drape and proportions just right. Stitching the pockets closed ensures that when you see the garment in a store, it looks exactly the way the designer intended. No sagging, no gaping, no uneven lines. The jacket hangs cleanly, and the visual impression is polished and intentional.
There’s also a subtler design philosophy at work. Designers know that once you start stuffing keys, phones, and wallets into hip pockets, the jacket’s silhouette changes completely. The fabric pulls, the front panels sag, and the balanced drape disappears. Keeping pockets stitched is partly a gentle nudge: even after you remove the thread, the habit of treating those pockets as decorative rather than functional helps the garment hold its shape for years. Men’s built-in pockets have always been limited in what they can hold without disrupting the line of a tailored ensemble, and overstuffed pockets are one of the fastest ways to age an otherwise well-made jacket.
How to Tell if a Pocket Is Real or Fake
Not every stitched-shut pocket is actually functional. Some garments, particularly in women’s clothing, have purely decorative pocket flaps with no pocket bag behind them. Before you start cutting thread, it’s worth checking.
- On unlined garments: Turn the piece inside out and look for two layers of pocket lining fabric sewn together behind the pocket opening. If they’re there, the pocket is real.
- On lined garments: Feel around on the inside for a pocket bag beneath the lining. You should be able to detect the extra layers of fabric.
- Check the stitching itself: Temporary stitches meant for removal are typically loose, clearly visible, and often a contrasting color. You may notice a small gap at either end of the seam. If the stitching is very tight, small, and blends seamlessly into the garment, the pocket is more likely decorative.
If you don’t find any pocket lining behind the flap, don’t try to force it open. There’s nothing behind it, and you’ll just damage the fabric.
Other Temporary Stitches to Look For
Pockets aren’t the only part of a new garment that comes temporarily stitched. The back vent of a blazer or coat (the slit at the bottom rear) is almost always sewn shut with the same kind of loose thread. That vent needs to open so the jacket moves properly when you walk. Leaving it stitched creates an awkward pull across the back and defeats the purpose of the vent entirely.
Brand labels on coat sleeves are another one. That small fabric tag near your wrist with the brand name is a retail identifier, not a design element. Snip the thread holding it on before wearing the coat. Similarly, some trousers come with temporary stitching along the hem or with tacked-down pleats that are meant to be released.
How to Remove the Stitches Safely
A seam ripper is the ideal tool. It has a sharp point for sliding under stitches and a small ball on the opposite tip that prevents you from accidentally piercing or snagging the fabric. The cutting edge sits in the curved groove between the two points.
Start at one end of the stitching. Slide the sharp tip sideways under a stitch, keeping the tool parallel to the fabric rather than pushing straight down into it. Gently pull upward to cut the thread. Work stitch by stitch along the seam, then pull the loose thread remnants free from both sides. Small scissors or tweezers can help clean up any remaining bits of thread.
The whole process takes under a minute per pocket. If the stitches are very small and you’re having trouble seeing them, working in bright light or using a magnifying lens helps. The key precaution is always moving the blade sideways rather than straight into the fabric, which virtually eliminates the risk of cutting or snagging.
Should You Leave Any Pockets Stitched?
Some people deliberately leave their jacket pockets stitched even after purchase, and there’s a reasonable case for it. If you know you’ll be tempted to use them, keeping the stitching intact prevents the gradual stretching and sagging that comes from regular use. Chest pockets (the breast pocket with a welt opening) are fine to open since you’ll only place a light pocket square there. But the lower hip pockets on a blazer carry the highest risk of distortion if loaded up with everyday items.
A middle-ground approach: open the pockets but commit to keeping them empty, or limit their contents to something flat and light like a few business cards. The garment will hold its intended shape far longer than one whose pockets serve as daily cargo storage.
