Sewing a lined jacket means constructing the outer shell first, then attaching a separate fabric layer inside to hide seams and add structure

A lined jacket looks finished on the inside and hangs better than an unlined one because the lining reduces friction and adds weight. The basic process is: sew the outer fabric pieces together, sew the lining pieces together separately, then join them at the armholes, neckline, and front edges before closing the bottom opening by hand. The lining floats inside rather than being sewn to every seam, which is what makes it look professional.

This is not a beginner project—you need to be comfortable with setting sleeves, grading seams, and hand-stitching. If you have made a straightforward unlined jacket or a dress with set-in sleeves, you have the foundation. A pattern designed for a lined jacket will guide you through the order of assembly, which matters more than the individual techniques.

Key Takeaways

  • Construct the outer jacket shell completely—body, sleeves, collar, and facings—before you touch the lining.
  • Sew the lining as a separate garment, then slip it inside the finished jacket and stitch it to the facing edges only.
  • The lining is attached at the neckline, armholes, and front facings, but left loose at the hem so it can move independently.
  • Grade (layer and trim) all seams in both the shell and lining to reduce bulk where they will be enclosed.
  • Hand-stitch the lining to the jacket hem using a ladder stitch so the stitches are invisible from the outside.

Prepare your pattern and fabric

Use a pattern specifically drafted for a lined jacket—do not try to adapt an unlined pattern. Lined jacket patterns include separate lining pieces and specify which edges get facings (usually the front, neckline, and armholes). Common pattern sources are Simplicity, McCall's, Vogue, and Burda, or independent designers like Grainline Studio and Closet Core.

Read through the entire pattern instruction sheet before cutting. Note which pieces are cut from fashion fabric (the outer shell), which from lining fabric, and which from interfacing. Lay out and cut all pieces at once—fashion fabric, lining, and interfacing—so you do not lose track of which is which. Mark grain lines, notches, and construction marks with tailor's chalk or a fabric pencil.

Press all fabric pieces with a dry iron before sewing. Lining fabric especially wrinkles easily, and wrinkles will show through the finished jacket. If your fashion fabric is prone to fraying (like linen or loosely woven wool), finish the raw edges of the outer shell pieces with a zigzag stitch or serger before assembly.

Construct the outer jacket shell

Sew the jacket body, sleeves, and collar exactly as you would for an unlined jacket. This means: attach interfacing to the front facings and collar pieces, sew the shoulder seams, attach the collar, sew the front facings to the front edges and neckline, sew the underarm and side seams, and set the sleeves. Press each seam as you go.

Grade all seams in the shell—this means trimming the seam allowances to different widths so they do not create a thick ridge under the lining. For a two-layer seam (like a shoulder seam), trim one layer to 1/4 inch and leave the other at 5/8 inch. For a three-layer seam (like a neckline with facing), trim the innermost layer shortest, the middle layer medium, and the outermost layer longest. Clip into curved seams like armholes and necklines every 1/2 inch so they lie flat when turned.

Turn the jacket right-side out. Press the front facings, neckline, and armhole edges so they are crisp and flat. The jacket shell is now complete and ready to receive the lining.

Construct the lining as a separate garment

Sew the lining pieces together using the same seams as the outer shell: shoulder seams, underarm seams, and side seams. Do not attach sleeves to the lining yet. Press all seams open. Grade the seams in the lining the same way you graded the shell seams.

Sew the lining sleeve seams and press them open. Do not set the lining sleeves into the lining body yet—they will be attached after the lining is inside the jacket. Leave the lining inside-out for now.

The lining should be slightly smaller than the shell so it does not pull or wrinkle. If your pattern does not account for this, trim 1/2 inch from the armhole seam allowance of the lining pieces. This small reduction prevents the lining from being too snug.

Attach the lining to the jacket at the facing edges

Slip the lining inside the jacket, both still inside-out. Match the shoulder seams of the lining to the shoulder seams of the shell. Pin the lining to the front facings and neckline facing, right sides together, along the outer edge of the facing. The lining should cover the facing completely.

Sew the lining to the facing using a 5/8-inch seam allowance, following the seam line that attaches the facing to the jacket. Sew around both front edges and the entire neckline. Backstitch at the start and end. Grade this seam: trim the facing seam allowance to 1/4 inch and leave the lining seam allowance at 5/8 inch.

Turn the jacket right-side out by reaching through one armhole and pulling the shell through. The lining will now be on the inside, with its edges sewn to the facings. Press the front and neckline edges so they are smooth.

Set the lining sleeves and close the armholes

Pin the lining sleeves into the lining armholes, matching the underarm seams and any sleeve cap markings. The lining sleeve should be slightly loose—do not pull it tight. Sew the lining sleeves in using a 5/8-inch seam allowance, the same way you set the outer sleeves. Grade the seam by trimming the lining seam allowance to 1/4 inch.

Fold the raw edge of the lining at the armhole under by 5/8 inch and press. Pin this folded edge to the inside of the jacket armhole, covering the seam where the outer sleeve is attached. The fold should just meet the seam line—not overlap it. Hand-stitch the folded lining edge to the armhole seam using a ladder stitch, taking small stitches (1/8 inch) and catching only one or two threads of the seam allowance so stitches do not show on the outside.

Close the jacket hem and lining hem separately

Fold the raw bottom edge of the jacket shell up by your hem allowance (usually 1 to 1.5 inches) and press. Fold the raw bottom edge of the lining up by the same amount and press. The lining hem should be about 1/2 inch shorter than the shell hem so it does not show at the bottom edge.

Hand-stitch the shell hem using a ladder stitch or blind stitch, catching the fold of the hem and the jacket body with small, invisible stitches. Then hand-stitch the lining hem the same way, keeping it separate from the shell hem. Do not sew the lining to the shell at the hem—this allows both layers to move independently and prevents pulling.

Press the finished hem from the outside. The lining should not be visible from the outside edge, and the inside should look neat with no raw edges showing.

Frequently Asked Questions

What is the difference between a lined jacket and a jacket with a facing?

A facing is a separate piece of fabric sewn to an edge (like the front or neckline) and turned to the inside to finish that edge. A lining is a full layer of fabric that covers the entire inside of the jacket. A lined jacket usually has both: facings to finish the edges and a lining to cover the inside seams and add structure.

Can I use cotton fabric for the lining?

Yes, but lining fabric is better because it is smoother and more slippery, so the jacket slides on and off easily. Cotton lining works but will create more friction. Avoid heavy fabrics like denim or canvas for lining—they add too much weight and bulk. Lightweight cotton, cotton sateen, or traditional lining fabrics like acetate or rayon are all suitable.

What if I sew the lining to the hem by mistake?

Carefully pick out the stitches with a seam ripper and re-stitch the lining hem separately. If the stitches have damaged the fabric, you may need to trim a small amount from the lining hem and re-fold it. This is why many sewers leave the lining hem for last—it is easier to fix if something goes wrong.

How do I prevent the lining from twisting inside the jacket?

Make sure the lining shoulder seams are pinned and sewn to match the shell shoulder seams exactly. If the lining is twisted at the shoulders, it will twist throughout the entire jacket. Also, trim the lining armhole seam allowance smaller than the shell so the lining sits slightly loose rather than tight.

Do I need to interface the lining?

No. Interface only the outer shell pieces that need structure, like front facings and collar pieces. The lining does not need interfacing because it is not meant to hold a shape—it is meant to drape and move inside the jacket.
