Vizzy invisible Zips 30-35cm

This is the 30-35cm Vizzy Invisible Zip range, suited to dress and skirt openings in that length where a hidden, seamless finish is wanted rather than a visible zip tape. The colour selection is broad, from neutrals like white, black and bone to shades such as dusty green, grape, mustard and dark maroon. A small range of Birch invisible zips in 30cm (black, white, cream) is also included here.

Choose this length for longer dress openings than the 25cm size, and pick the colour closest to your fabric for the cleanest result. Since these are fixed-length zips, check the opening measurement on your garment or pattern before ordering.

Frequently asked questions

What's the difference between Vizzy and Birch invisible zips in this range?

Both are invisible zip styles that hide in the seam; Birch is a separate brand offered here in a smaller colour selection (black, white, cream) compared with the wider Vizzy range.

How do I choose between 30-35cm and other lengths?

Measure the zip opening on your garment or pattern. This range suits longer openings than 25cm zips; shorter options are available elsewhere if needed.

Why use an invisible zip instead of a standard dress zip?

An invisible zip sits hidden within the seam for a cleaner finish, while a standard dress zip is visible on the outside of the garment.
