It has been too long: I've been very busy.
Lots of vintage patterns feature side zips. There are obvious advantages to having the zip at the side rather than back or front:
- It can't be seen, from a design point of veiw this is almost always preferable;
- If the fabric has a pattern it negates the need to pattern match the back seam;
- It frees up the neckline to incorporate collars or other design features.
However there are two issues with having your closure at the side:
- If your back is not the standard size altering the pattern will be more complex;
- Altering the fit at a later date due to fluctuations in size is far more problematic.
5. Turn your dress to the right side. This automatically brings the zipper into its rift place. Baste the front edge of you placket to the zipper tape, basting 3/8" back from the seam.
6. Take out basting which is holding the placket together.
7. Assuming you are happy with the position of your zipper, stitch and remove basting.
Because we stabilised the seam, it should sit flat to the zipper.
I will be posting updates on our summer sew-along soon.
