Sewing a lined vest means attaching an inner fabric layer to the outer shell so the seams stay hidden and the vest keeps its shape
A lined vest looks polished because you never see the raw seams or thread ends on the inside. The lining also makes the vest easier to slip on and off, and it reinforces the armholes and neckline so they hold up through wear. The basic process is: cut both outer and lining pieces, sew the outer vest together, sew the lining together separately, then stitch them together with right sides facing so you can turn the whole thing inside-out and have a finished edge all the way around.
This method works for any vest pattern—whether you are making a straightforward sleeveless shell or a structured tailored vest. The key difference from an unlined vest is that you sew the outer and lining as two separate units first, then join them as one step. This takes a bit longer but gives you a professional finish that looks the same on both sides.
Key Takeaways
- Cut two complete sets of vest pieces—one for the outer fabric and one for the lining—using the same pattern.
- Sew the outer vest and lining vest separately, leaving one seam partially open so you can turn the vest right-side-out later.
- Pin the outer and lining pieces with right sides together, then sew around all edges except the armholes, which you finish by hand or machine after turning.
- Turn the vest through the opening, press it flat, and close the opening with a ladder stitch or machine stitching.
- Topstitch around the neckline and armholes if you want a crisp, tailored look and to hold the lining in place permanently.
Gather your fabric, pattern, and tools before you start
You will need two fabrics: one for the outer vest (cotton, linen, wool, or a blend) and one for the lining (cotton, silk, or a lightweight synthetic). The lining should be slippery enough to slide easily over your arms but sturdy enough not to tear. Avoid very heavy lining on a lightweight outer fabric, as the weight imbalance will make the vest hang unevenly.
Lay out your vest pattern on both fabrics and cut all pieces—front panels, back panel, and any facings or trim pieces—exactly the same way for both outer and lining. Mark all notches, darts, and grain lines with tailor's chalk or a fabric pen so you can match them up later. Have your thread, pins, scissors, iron, and sewing machine ready. A seam ripper is helpful for fixing mistakes without starting over.
Sew the outer vest shell first, leaving one seam open
Lay out your outer fabric pieces with right sides together (the pretty sides facing each other). Pin the front panels to the back panel at the shoulder seams, matching all notches. Sew these seams with a straight stitch at a standard 5/8-inch seam allowance, backstitching at the start and end to lock the thread.
Next, sew the side seams, but stop stitching about 4 inches before you reach the bottom hem. This opening is where you will turn the vest right-side-out later, so leave it unsewn for now. Press all seams open with your iron to flatten them. If your pattern includes darts or waist shaping, sew those now on both the outer and lining pieces before you join them.
Construct the lining vest the same way
Using your lining fabric, repeat the exact steps: pin the front panels to the back at the shoulders, sew with right sides together, then sew the side seams and leave the same 4-inch opening on one side. Press all seams open. The lining should now be an identical shell to your outer vest, just in a different fabric.
Check that both vests fit the same way and that all seams line up when you hold them together. If one is slightly larger or smaller, you may have cut the pieces at different sizes—measure across the shoulders and down the side seams to confirm they match. Small differences will show when you wear the vest.
Pin the outer and lining together, right sides facing
Turn your outer vest right-side-out (so the pretty fabric shows on the outside). Keep your lining vest inside-out. Slip the outer vest inside the lining vest so they are nested together with right sides touching. The wrong sides of both fabrics now face outward.
Pin around the entire neckline, starting at one shoulder seam and working your way around. Match the shoulder seams, side seams, and any notches so the two vests line up perfectly. Pin every 2 to 3 inches and check that there are no twists or bunches. Then pin around both armholes the same way, matching all seams.
Sew the neckline and armholes, then turn the vest right-side-out
Sew around the neckline with a 5/8-inch seam allowance, backstitching at the start and end. Use small stitches (about 2.0 on most machines) so the seam is strong and the curve lies flat. Sew around both armholes the same way. Trim the seam allowance down to 1/4 inch and clip small notches into the curves every 1/2 inch so the fabric will curve smoothly when you turn it.
Reach through the side opening you left unsewn and grab the outer vest. Pull it through the opening so the vest turns right-side-out. The lining is now on the inside and the outer fabric is on the outside, with finished seams all around the neckline and armholes. Press the neckline and armholes flat with your iron, rolling the seam to the very edge so no lining shows from the outside.
Close the side opening and finish the hem
Fold the raw edges of the side opening inward by 5/8 inch on both the outer and lining pieces. Pin them closed. You can now sew this opening shut by machine with a straight stitch, stitching very close to the fold so the seam is nearly invisible. Alternatively, use a ladder stitch (also called an invisible stitch) by hand: thread a needle, knot the end, and slide the needle inside the fold of one side, then across to the fold of the other side, then back and forth in a zigzag pattern. The thread stays hidden inside the fold and the opening closes without a visible seam line.
Press the entire vest flat. If your pattern includes a hem at the bottom, fold it up 1/2 to 1 inch and pin it in place so the lining and outer fabric fold together as one. Sew the hem by hand with a blind stitch or by machine with a straight stitch close to the fold.
Topstitch the neckline and armholes for a polished finish
Topstitching is optional but gives your vest a tailored, finished look and locks the lining permanently in place so it will not shift when you wear it. Thread your machine with thread that matches your outer fabric. Starting at a shoulder seam, sew around the neckline about 1/4 inch away from the edge, using a straight stitch. Backstitch at the start and end. Repeat around both armholes.
Press the vest one final time and try it on. The lining should lie flat against your body without bunching, and the outer fabric should drape smoothly. If the lining pulls or wrinkles, you may have sewn it too tightly—this is a common mistake. If this happens, you can loosen the topstitching slightly or add a small pleat at the side seams on the inside to give the lining a bit more room.
Frequently Asked Questions
What if I sewed the side seam all the way closed by accident?
Use a seam ripper to carefully cut and remove 4 to 6 inches of stitching from one side seam, then turn the vest right-side-out through that opening. Once it is turned, you can close the opening by hand with a ladder stitch or by machine. It is not ideal, but it works and will not show once the vest is finished.
Can I use a stretchy fabric like jersey or knit for the lining?
Stretchy lining can work if your outer fabric is also stretchy, but a woven lining is easier to work with because it does not shift as you sew. If you use knit lining, use a ballpoint needle and sew slowly so the seams do not pucker. Test on a scrap first.
How do I keep the lining from showing at the armholes when I move?
Make sure your armhole seam allowance is trimmed to 1/4 inch and clipped well so it curves smoothly. Press it toward the lining side (not the outer fabric) so the lining sits slightly inside the armhole edge. Topstitching around the armhole also helps hold everything in place.
Should the lining be the same size as the outer vest?
Yes, cut both from the same pattern pieces. If you make the lining smaller to reduce bulk, it will pull and wrinkle. If you make it larger, it will bunch inside. Matching sizes ensures the vest hangs evenly and the lining stays in place.
What is the best thread color to use?
Use thread that matches your outer fabric for the seams that show (neckline and armholes). For the side seams and other hidden stitching, use thread that matches either fabric—it will not be visible. If you are topstitching, use a thread color that complements your outer fabric or matches it exactly for a subtle look.
