How to stitch zipper on a dress
I found from this vintage fashion site that no one has worn centre back zipper dresses before 1940’s. Infact the modern zipper was invented in 1914 but got used in clothes only by late 1930’s. Now they are so much a part of dresses, you cannot imagine dresses and gowns without them.
I am a self taught sewist and Zippers used to look intimidating to me earlier. After some trial and error I have found that it is one of the simplest things to sew if you know how to. I am not talking about invisible zipper and such but the simple ordinary dress zipper.
You will have to see if the pattern has a center seam first. If it has, you can sew the zipper centered on the back seam or a little lapped i.e it will look like a small flap is there on top of the zipper. The third method involves sewing zipper when there is no center seam. Check it out.

To sew zipper on a dress you need two things
- Ordinary zipper – They come in many length and colours. Choose a colour close to your dress. Even if you get a very long zipper do not worry, you can always cut the extra out and then make a zipper stopper stitch. ie mark the length you want your zipper opening to be on the zipper. Add an inch or two and make a basting stitch or a machine zig zag stitch connecting the two sides of the zipper teeth together. Now you have a zipper stop stitch. If you dont do this the zipper will seperate before you manage to sew it to the dress.
- Zipper foot – This is a life saver when you sew the zipper. In a clinch you can use the regular foot of course. If you haven’t used a zipper foot yet, take it out of your sewing box. You most probably got it free with your sewing machine. This foot is a narrow one like a square spoon, with a notch in the left and right for needle. With this zipper foot you can sew really close to that zipper teeth. With a regular foot there will be a space between the stitching line and the zipper opening which is unbecoming.
Note : Please take care that, even while it is essential that we stitch close to the zipper teeth as possible ( which is why we use a zipper foot), you should not sew over the zipper teeth at all. The zipper teeth would not close if you do this. Go slowly when sewing zipper and make sure that even when you cannot see the zipper or the needle you are feeling with your fingers.
How to sew the zipper if the dress has a center seam ?
Method 1. How to sew a Centered zipper ?
This is a case where there is a seam in the middle of the back pattern. This zipper insertion is very easy.

fabric so that right side is facing you.
Run a few stitches parallel to the pin you have placed on the mark for bottom of the zipper. Back stitch here if you want to.

Step1. Sew a plain seam for the center seam leaving the zipper opening. Now baste the zipper
opening by hand stitching or machine with long basting stitches.
