Keyhole neckline : 10 best placements & How to sew one

keyhole neckline

What is a Keyhole neck ? 

As the name suggests, keyhole neckline has a keyhole cut away along the neckline.  The keyhole usually has a slightly convex shape and the top of the convex shape may be left open or joined together at the top edge of the neckline (usually with a closure). Other shapes of the keyhole neckline include a teardrop shape, an oblong shape etc. It is an appealing neckline as it takes away the severity of a regular plain neckline.

Different styles of keyhole neckline 

1. Simple straight keyhole neckline

This kind of neckline is cut straight down on the central fold of the bodice. Check out this post on making a Kurta tunic to learn how to make this type of neckline.

2. Regular keyhole neckline

This has a correct convex shape with the top secured with a metal hook and eye.

3.Keyhole placed to the side

Here the keyhole is placed to one side of the neckline rather than on the center of the neckline

4. Keyhole in the back

5. Keyhole joined with bead chain/buttons

How to sew a keyhole neckline

Cut out a facing for the neckline – the red line indicates the stitching line – here I have drawn a straight keyhole. For a convex shape you have to draw that shape.

Keep the facing on top of the bodice.

Sew the neckline. As you reach the end take a single stitch across (rather than bring it to a point) – this will create a small space there which will make the turning smooth.

Cut out the extra – leave 1/4 seam allowance. Especially important is to cut  to the end of the bottom point.

Clip the seam all along – the red lines in the picture indicates where you should clip.

Turn the facing to the right side.

    I have an open key hole neckline that one side wants to fold under. How can I fix this?

      You can add a stay tape under the edge to make it stiffer.

    Hello, I’m trying to follow this tutorial for a dress I’m making. I’m interested to see how the facing looks once it’s turned to the right side, and how it’s sewn down.

    This article is really helpful in my attempt to convert a too-deep “V” neck to a round/keyhole neck. Thank you!

    Thank you for the easy to follow explanation. If my original pattern has a bias binding finish, should i extend the new faceing to include the back of the neck?

    Thank you for indicating that you need to take a stitch at the bottom of the V! This step is so often left out of directions but is so important in making the keyhole facing lay flat!
