Sew a Lined Skirt with an Invisible Zipper: Step-by-Step Guide

Sewing a lined skirt is a fun, satisfying project that produces a polished, wearable result. This clear, step-by-step guide will show you how to make a half circle skirt with a lining and an invisible zipper — no commercial pattern needed. With simple measurements and basic sewing skills you can make a knee-length skirt that fits well and looks professional.

Whether you’re new to sewing or an experienced stitcher, a lined half circle skirt is an achievable project. If you tried a full circle skirt tutorial before, you’ll find this half circle version even easier — especially once you get comfortable inserting a zipper. The zipper can feel like the trickiest part, particularly when adding a lining, but with careful pinning and a zipper foot it’s straightforward.

This tutorial has a PDF version for sale, but the article below is completely free to read.

Before you start, you may want to review a short tutorial on inserting a zipper into a lined skirt if you haven’t done it before. The zipper step is the main one to pay attention to; follow the zipper instructions carefully and the rest of the construction will fall into place.

How to sew a lined skirt

Materials:

Measuring tape or a long ruler
Pen or pencil
Marker
Pattern paper or any large paper for drafting
About 2 yards of fabric for the skirt (cotton is great for beginners)
About 2 yards of fabric for the lining (lightweight cotton or similar)
Zipper (length depends on how tall you want the opening)
Interfacing for the waistband (optional; fold fabric for stiffness as an alternative)
Scissors
Zipper foot for your sewing machine
Matching thread and a contrasting thread if desired
Pins
Pressing iron
Sewing machine

Instructions:

Making the half circle skirt pattern

Measure your waist. Add 1″ to that measurement, then divide by 3.14 (π) to calculate the waist radius (this is the inner circle). Round to the nearest quarter inch.
Decide the skirt length from the waist to the desired hemline and add 2″ for seam and hem allowances. This gives you the hem radius (outer circle).
On a large piece of paper, draw the inner circle. Start the circle away from the paper corner and use the measuring tape as a compass, marking points as you go.
From the inner circle, measure outward the length you chose to draw the outer circle. This creates the half circle pattern piece. Cut along both circles — this will be half your skirt pattern.

Double-check measurements: the inner curve should match your waist radius and the outer curve the desired hemline.

Once cut, this pattern piece represents one half of the skirt. You’ll cut two mirrored halves from the fabric to form the full skirt.

Preparing the fabric

Fold the skirt fabric in half, right sides together, with the fold along the top and the selvedges down each side.
Place the half circle pattern so the inner circle aligns with the folded corner, pin, and cut around both curves. Repeat for the lining fabric.

After cutting, you should have two skirt halves and two lining halves.

Sewing the skirt

With right sides together, sew the side seam of the skirt. Finish the seam with a serger or a zigzag stitch to prevent fraying.
Repeat the same seam construction for the lining pieces.
Switch to a zipper foot on your machine before attaching the zipper.
Mark how long you want the zipper opening to be, and allow space at the top of the lining for the waistband and zipper stop.
Insert the zipper between the skirt and lining following zipper insertion steps — pin carefully and stitch with the zipper foot so the zipper tape sits neatly along the seam.

Making the waistband

Cut a waistband strip to match the waist measurement plus 1″ (the inner circle circumference allowance).
Cut interfacing slightly shorter than the waistband length and inset from top and bottom by about 1/2″ so the interfacing doesn’t show at the finished edges.
Fuse the interfacing to the wrong side of the waistband with an iron. Fold under the top and bottom edges, then fold the waistband in half and press for a crisp finish.

Attaching the waistband to the skirt

Pin the skirt and lining together at the inner circle and stitch with a narrow 1/8″ seam to keep them aligned when attaching the waistband.
Slide the pressed waistband over the top edge of the skirt and lining. Pin the raw folded edges of the waistband to the skirt’s top edge, hiding the zipper tape inside the waistband as needed. Trim the top of the zipper if it’s too long and position the zipper pull so it moves freely.

Sew the pinned waistband seam, then flip the waistband up and press. Fold the inner edges of the waistband over to cover raw edges and pin on the inside.

From the inside, fold the remaining waistband edges to cover the raw edges of the skirt and lining, then pin in place.

Topstitch from the right side about 1/8″ from the previous seam to secure the back of the waistband and give a clean front finish.
Sew across the top of the zipper to catch the zipper tape and complete the waistband.

Switch back to a regular presser foot and press the waistband and seams well.
Finish the hem to your preference — a narrow double fold or rolled hem works well for lightweight fabrics.

And that’s it — you now have a lined half circle skirt with a neat waistband and zipper. Wear and enjoy!

Tips for sewing this lined skirt

Use medium-weight interfacing to reinforce the waistband for added structure. If you don’t have interfacing, fold the waistband fabric to achieve the same firmness.
A zipper foot makes attaching the zipper much easier and produces neater stitching along the zipper tape.
Trim the top of the zipper before attaching it to avoid bulk inside the waistband and to get a smooth finish.
Take your time with the waistband: hide raw edges and press well for a clean, professional look.
Try different fabrics and colors — a contrasting waistband or lining can add visual interest.

Variations of this project

Add pockets for extra convenience and function.
Adjust the length to make a mini, knee-length, or midi skirt.
Finish the hem with contrasting bias tape for a decorative touch.
Convert the shape to a full circle or an A-line silhouette for a different drape and fullness.
Use a contrasting lining that peeks from beneath the hem for a playful pop of color.
