The collar is one of the most defining features of a polo shirt. It adds structure, sophistication, and separates the polo from a basic tee. However, after multiple washes and wears, you might notice your collar starting to curl, wrinkle, or go completely limp. This is a common issue caused by heat exposure, fabric shrinkage, or improper storage.
When collars lose their shape, it immediately affects the overall appearance of your polo shirt. A curled or floppy collar can make even the most expensive shirt look tired and unkempt. Thankfully, you don’t have to retire your favourite polo just because the collar isn’t behaving. With a few simple techniques, you can restore its sharp, clean look and extend the shirt’s lifespan.
Fixing the collar also helps the shirt lay properly on your body, making it easier to layer with jackets or blazers, and maintaining that versatile smart-casual edge that polos are known for.
Understanding the Common Collar Problems
Collar Curling
One of the most frustrating polo issues is when the collar starts curling upward or downward along the edges. This typically happens when the outer fabric and the inner lining shrink at different rates during washing and drying. The result is a warped edge that won’t lie flat, no matter how much you smooth it out.
High heat from dryers is a major contributor, especially when polos are dried without being properly reshaped. Cheap or worn-out interlining can also lose its rigidity over time, causing the collar to curl even more with each wash. To fix this, steaming or ironing with precision can help reset the fabric and bring the collar back into form.
Wrinkled Collars
Wrinkles in the collar area may not seem as severe as curling, but they still disrupt the shirt’s polished appearance. Wrinkles are often the result of letting your shirt sit in the dryer too long, folding it incorrectly, or stuffing it into a drawer without care. Over time, these creases can become embedded in the fabric, especially in pique or cotton materials.
Frequent laundering without pressing or steaming allows wrinkles to accumulate. While these wrinkles may flatten temporarily with wear, they rarely go away without some sort of heat treatment. A quick steam or light iron can usually restore the collar to a smooth, structured finish.
Limp or Floppy Collars
A polo collar that’s lost its structure entirely—soft, droopy, and unable to stand or fold properly—is another common issue, especially in older shirts or those made from softer fabrics. This is typically caused by overuse, repeated stretching during wear, or weakened fabric from excessive washing.
Without the internal stiffness that gives the collar its shape, it begins to sag and can even collapse under its own weight. While fixing a floppy collar can be trickier than curling or wrinkling, targeted ironing with starch or interfacing tape can bring it back to life, at least temporarily. In some cases, reinforcing the collar with an iron-on patch underneath may be necessary. See our gym tracksuit womens
Step-by-Step Guide to Fixing Polo Shirt Collars
Step 1 — Wash and Rinse the Polo Shirt Properly
Before attempting to fix your polo collar, it’s important to start with a clean shirt. Wash the polo according to its care label instructions. Typically, this means using cold or lukewarm water on a gentle cycle. Avoid hot water, which can shrink the fabric unevenly and worsen curling around the collar area.
Use a mild detergent to preserve the fabric’s softness and structure. Avoid bleach or strong stain removers on the collar, as they can weaken the interlining and make it more prone to curling or wrinkling in the future. After washing, gently squeeze out excess water. Don’t wring or twist the collar, as that can warp its shape even further.
Step 2 — Flatten the Collar After Washing
As soon as your polo shirt is out of the wash, lay it flat on a clean, dry towel or drying rack. Before it begins drying, take a few moments to reshape the collar by hand. Smooth out the edges, straighten the collar points, and press it flat with your palms.
This step is crucial because once the fabric starts drying, it tends to set in whatever shape it’s left in. If you leave the collar crumpled or curled, those imperfections will become harder to fix later. Avoid hanging the polo while it's wet gravity can cause the damp collar to droop or stretch. Keeping it flat helps maintain its natural form until you're ready to iron.
Step 3 — Use a Steam Iron to Restore Shape
After the shirt is partially or fully dry, it’s time to restore the collar using a steam iron. Set your iron to the “cotton” or “steam” setting, depending on the fabric blend. If your shirt is made of delicate or blended materials, use a lower heat setting and test a small area first.
Place a thin cotton cloth, like a handkerchief or tea towel, over the collar to protect the fabric from direct heat. Begin ironing by gently pressing along the length of the collar, starting from the centre and moving toward the tips. Use light pressure and let the steam relax the fibres.
The combination of moisture and heat will help smooth out wrinkles, flatten curls, and restore the collar’s structure. Don’t rush this process; move the iron slowly and steadily to avoid creating new creases.
Step 4 — Apply Starch Spray for Structure
To achieve that crisp, structured look you often see on brand-new polo shirts, a light starch spray can make a big difference. After ironing once, lightly mist both sides of the collar with fabric starch spray available at most grocery or laundry stores.
With the collar still protected by a cloth, iron again using the same smooth motion. The starch helps stiffen the fabric and hold the flat shape longer, giving your collar a refreshed, polished look. Don’t over-saturate; just a light spray is enough to add structure without making the fabric stiff or flaky.
This step is especially helpful for polos that tend to develop floppy or limp collars over time. It won’t permanently solve the issue, but it gives your shirt a temporary lift that lasts through multiple wears.
Step 5 — Dry and Store Properly
Once the collar is flat, smooth, and crisp, hang the shirt up immediately. Use a wide, padded hanger to maintain the shoulder shape and keep the collar from getting crushed. Make sure the top button is fastened or the collar is gently folded down in its correct shape.
Avoid overstuffed closets or tossing your polo in a drawer where the collar can get bent. If you prefer to fold your polos, make sure the collar lies flat and isn’t tucked under any part of the shirt.
Consistently drying and storing your polos the right way helps maintain the collar’s form between washes and reduces the need for frequent ironing. With just a little aftercare, your polo shirt can keep looking crisp, clean, and well-structured for seasons to come.
Alternative Fixes for Stubborn Collars
Using Collar Stays or Inserts
If your polo shirt collar just won’t stay down, even after ironing and starching, collar stays or inserts can offer a quick and reliable fix. While most polo shirts don’t come with built-in slots for stays like dress shirts, you can use removable silicone or magnetic collar stays that stick to the inside of the collar or are placed between fabric layers.
These products are thin, flexible, and designed to discreetly hold the collar flat throughout the day. They’re especially useful if you’re wearing a polo under a blazer or at a smart-casual event where you need your shirt to stay crisp. Some collar stays use adhesive patches, while others rely on friction or magnets, so you can choose one based on your comfort level and shirt material.
This solution works best on thicker, structured polos rather than ultra-lightweight performance fabrics. It’s a handy option to keep in your wardrobe for those polos that look great but just don’t want to behave.
Replacing the Collar Interlining
For polos with collars that have gone completely limp, the issue may lie in the interlining, the inner layer that provides structure and stiffness. Over time, washing and wear can break this down, especially in budget or older polos.
If you’re dealing with a shirt you really love and want to rescue, consider taking it to a tailor or alterations specialist. They can open up the collar seam, replace the worn-out interlining, and resew it to restore its original shape and sharpness. This is a more involved fix, but it’s worth it for high-quality or designer polos.
In some cases, tailors can even upgrade the interlining to a firmer material, giving your collar a cleaner and longer-lasting structure than before. It’s a professional solution for collars beyond home repair, especially when other methods don’t cut it.
DIY Hack — Hair Straightener or Flat Iron
Need a quick fix before heading out the door? A hair straightener or flat iron set to low heat can act as a compact alternative to a full-sized steam iron. It’s perfect for targeted areas like curling collar tips or small wrinkles that appear after storage or travel.
Make sure the straightener is clean and free of any hair products or residue. Clamp it gently over the collar edge, moving it slowly along the fabric. Use a pressing cloth if you’re worried about direct contact, especially with delicate materials or prints.
This hack works best when you're in a rush or don’t have access to a steam iron. Just remember to use the lowest heat setting and avoid pressing too hard, you want to smooth, not scorch.
Preventing Future Collar Damage
Avoid Machine Dryers
One of the leading causes of curled, limp, or misshapen collars is machine drying, especially on high heat. While convenient, dryers can shrink and twist the collar area, breaking down the interlining and setting in curling that’s hard to reverse.
To prevent future damage, air dry your polos flat on a towel or a mesh drying rack. This preserves the shape of the entire shirt, especially the collar. If you must use a dryer, stick to a low-heat setting and remove the shirt while it's still slightly damp, then smooth the collar by hand and finish drying it flat.
Air drying not only protects your collars but also extends the overall lifespan of your polo shirts.
Fold or Hang Correctly
How you store your polo shirt plays a big role in how the collar holds up over time. Avoid folding the collar under or cramming it into overstuffed drawers. This causes creases and curling that become permanent with repeated pressure.
The best option is to hang your polo shirt on a wide, soft hanger and keep the top button fastened or the collar gently smoothed down. If you prefer folding, lay the collar flat and avoid folding it over itself. Store polos in neat stacks with the collar resting on top to reduce pressure on the fold line.
Proper storage keeps your collars looking fresh and helps your shirt stay ready to wear without needing extra ironing.
Iron After Every Few Wears
Even if you’re not washing your polo after every use, giving the collar a light press can make a big difference. A quick pass with a steam iron or garment steamer every few wears helps maintain the collar’s structure and prevents light creases from becoming deeper wrinkles.
This simple step keeps your polos looking polished without having to do a full wash and iron each time. It also helps reinforce the collar’s fold line, so it lies naturally when worn. Adding this to your weekly routine is an easy way to extend your polo’s lifespan and keep it looking crisp all season long.
Conclusion
Fixing a polo shirt collar is a simple process that can dramatically improve the overall appearance and longevity of your shirt. Whether you're dealing with curling edges, wrinkles, or a limp fold, a few mindful steps like proper washing, hand-flattening, steam ironing, and starching can bring your collar back to life.
And prevention is just as important. By air drying, storing your polos correctly, and maintaining the collar between wears, you’ll preserve that neat, polished look that makes polos such a versatile and stylish wardrobe staple.
A little extra attention to your polo collars goes a long way, not only saving you from unnecessary replacements but also helping you present a cleaner, sharper version of yourself every time you step out.
