Invisible zips (aka concealed zippers) are a fantastic string to any dressmaker’s bow. The invisible zipper foot means inserting them couldn't be easier. Sewing as closely as possible to the fastener is crucial in achieving success with invisible zippers, and this foot accomplishes that by slightly unrolling the zipper. Once it’s been fitted, your zip will simply look like part of the seam.

Top tips for installing a perfectly concealed zipper

We don't recommend pressing a concealed zipper open before sewing as the heat may damage the coils of the zipper.
Begin by installing the left-hand side of the zipper using a concealed zipper foot to get a flawless finish.
Close the zipper and, on the unsewn side of the zipper, mark the waist seam point on the WS of the tape with a fabric pencil.

Position the zipper on the other side of the dress and temporarily pin. Baste the zipper in place around the waist seam with a needle. We recommend about an inch above and below the waist point.

5 Close the zipper and confirm your waist seam will match across the seam line or unpick and move until it will.

6 Stitch the other side in place with your concealed zipper foot and remove your basting stitches.
