How to make a polo placket?

The polo placket is a buttoning technique that allows you to partially open a neckline at the center front. It is found on polos, but also on some tops and dresses. It consists of two identical fabric strips and can be adjusted according to the desired width and length. Follow this detailed guide to make a polo placket with precision.

How to prepare the pattern?

• Mark the position of the placket

On the front neckline, mark the future position of the placket by drawing a vertical center line and defining the height of the opening. Then connect these marks with a perpendicular line. At the bottom of the drawing, form a small triangle 1 cm high. 

• Cut the fabric pieces

Cut two fabric strips along the grain with the following dimensions:

• Length = Opening height + seam allowances
• Width = (2 × seam allowance) + desired final width

Example:

• Length: 12 cm + 2 cm = 14 cm
• Width: (2.5 cm × 2) + 2 cm = 7 cm

How to position the strips?

• Fuse the wrong side of the fabric

Apply a piece of interfacing slightly larger than the width of the placket on the wrong side of the front of the garment. It should cover the drawn triangle.

• Reinforce the fabric strips

On the wrong side of the two cut strips, fuse only the half corresponding to the inside of the placket.

• Pin and position the strips

Place the two strips right sides together on the front of the garment, perfectly aligning the center lines and the fusible interfaced areas at the center front. Pin the edges to stabilize the assembly.

How to sew and open the placket?

• Make the first seam

Sew the strips following the drawn lines, using a straight stitch with a length of 2.5. The seams must stop exactly at the same point at the bottom of the future placket. Then press to flatten well.

Open the slit and prepare the finishes

• Cut along the center line down to the bottom of the slit.
• Then cut the sides of the triangle up to the last stitch, without going beyond.
• Trim the seam allowances so they measure about 0.7 to 1 cm.

Press to structure the placket well

With the iron, open the seam allowances for a neat fold. Also form the fold of the strips and press carefully.

How to form and attach the polo placket

• Fold and position the strips

Fold the strips toward the garment’s wrong side, pressing the folds well with the iron. Make sure the width of the strips is uniform along the entire height of the placket.

• Secure the top of the placket

If the neckline ends with a collar, fold the strips right sides together at the previous fold. Stitch at the top of each strip, from the fold to halfway down the placket. Start and finish with a backstitch. Trim the 5mm seam allowance and clip at its end.

• Turn and assemble the layers

Turn the top of the placket right side to wrong side to create a clean angle, then press. Then sew the seam allowance of the first strip, and repeat the operation for the second.

Overlap and finish the placket

• Check alignment and topstitch

Overlap the strips to check they are properly aligned and adjust if necessary. Then topstitch 2 mm from the edge to keep the edges filled and give a finished look. Baste first if you think it’s necessary.

• Fold and secure the bottom triangle

Fold the small triangle formed at the bottom of the slit wrong sides together, then topstitch to hold everything in place.

• Stitch and reinforce the layers

Sew one last stitch along the fold of the triangle, using a straight stitch and securely fastening all layers together. 

• Final ironing and finishing

Do a final press to flatten the placket well and give it a sharp finish. You can then continue assembling the garment.

Conclusion

The polo placket is an elegant and practical finish that adds a neat touch to garments. By following these steps, you will achieve a clean and functional opening, ideal for polos, shirts, and tops requiring partial buttoning. With good ironing and precise sewing, your polo placket will be perfectly made!
