Sewing a lined vest means making two fabric shells—an outer layer and a lining—then joining them at the armholes, neckline, and front edges so the seams stay hidden inside

A lined vest looks finished on both sides because the lining covers all your seams. You'll cut and sew the outer fabric first, then cut and sew the lining separately, then stitch them together with right sides facing so the seams end up sandwiched between the two layers. The whole process takes about four to six hours for a beginner, depending on how many details your pattern includes.

The key difference from an unlined vest is that you're essentially making two complete vests and then joining them. This means you need twice as much fabric—one length for the outer vest and one for the lining. Most vest patterns tell you how much of each you'll need; if yours doesn't, add up the yardage for all the pieces and double it.

Key Takeaways

  • Cut and sew the outer vest and lining as two separate garments before joining them together.
  • Press all seams flat and trim them to quarter-inch width before you join the two shells, so they lie flat inside the finished vest.
  • Stitch the outer and lining shells together at the neckline, armholes, and front edges with right sides facing, then turn the vest right-side-out through one of the side seams.
  • Topstitch around the neckline and armholes after turning to hold the lining in place and create a professional edge.
  • Close the opening in the side seam by hand with a ladder stitch so the closure is invisible.

Gather your materials and choose a pattern

You'll need two pieces of fabric—one for the outer vest and one for the lining. Outer fabric can be cotton, linen, wool, or a blend; lining is usually cotton, cotton-polyester blend, or a slippery synthetic like rayon. Lining fabric is thinner and smoother than outer fabric, which makes it easier to slip on and off. Buy the yardage your pattern calls for, plus a half yard extra for mistakes.

You'll also need thread that matches both fabrics (or a neutral color that works with both), a sewing machine, scissors, pins, a measuring tape, and a seam ripper. An iron is essential—you'll press seams multiple times, and pressed seams are what make a lined vest look professional. A pattern designed for a lined vest will include separate pieces for the lining; if your pattern doesn't mention lining, it's not designed for this method.

Cut out the outer vest and prepare the pieces

Lay out your outer fabric on a flat surface and pin the pattern pieces to it, following the grain line marked on each piece. Cut slowly and carefully—a sharp pair of scissors or a rotary cutter makes a cleaner edge than dull blades. You'll typically cut two front pieces, two back pieces, and possibly pocket pieces or facing strips, depending on your pattern.

Before you sew anything, mark the notches and construction lines on your fabric pieces. Use tailor's chalk or a fabric pen to mark where darts, pockets, or seams should go. These marks are your roadmap while you're sewing. Once everything is marked, you're ready to sew the outer vest together.

Sew the outer vest shell

Start by sewing any darts or construction details your pattern includes. Darts are small triangular seams that shape the fabric to fit your body; they're usually at the bust or back. Sew them with a straight stitch, backstitch at the beginning and end, and press them flat toward the center of the garment.

Next, sew the shoulder seams by pinning the front and back pieces together with right sides facing (the pretty sides touching). Sew with a quarter-inch seam allowance—that's the standard width. Backstitch at the start and end of every seam. Press the seams open or to one side, depending on what your pattern says. Then sew the side seams the same way.

At this point you have a complete outer vest shell. Press all the seams flat, then trim them down to a quarter-inch width using sharp scissors. This step matters: thick seams will create lumps inside the finished vest. Clip into curved seams (like armholes) every half-inch or so, cutting perpendicular to the seam line without cutting through the stitches. This lets the seam curve smoothly instead of bunching.

Cut out and sew the lining

Lay out your lining fabric and pin the same pattern pieces to it—front, back, and any other pieces your pattern includes. Cut them out the same way you cut the outer fabric. Do not cut armhole or neckline facings from the lining; the lining itself will be the facing.

Sew the lining pieces together exactly as you sewed the outer vest: darts first, then shoulder seams, then side seams. Press all seams flat and trim them to a quarter-inch, just as you did with the outer vest. Clip into curved seams. The lining shell should now be the same size and shape as the outer shell.

Leave one side seam of the lining unsewn—this is your turning opening. You'll use this gap to turn the whole vest right-side-out later. Mark it clearly so you don't accidentally sew it closed.

Join the outer vest and lining

Place the outer vest and lining with right sides facing (pretty sides together). Pin them together around the neckline, armholes, and front edges. The side seams should be aligned, and the shoulder seams should match up exactly. If they don't, adjust your pins until they do.

Sew around the neckline with a quarter-inch seam allowance, backstitch at the start and end, and remove pins as you go. Sew all the way around, then sew the armholes the same way. Finally, sew down both front edges. You should now have a complete vest with the outer and lining stitched together on three sides, and one side seam still open.

Trim all these seams to a quarter-inch width and clip into the curves at the neckline and armholes. This is crucial—thick seams will show as bumps on the outside of the finished vest.

Turn the vest right-side-out and close the opening

Reach through the unsewn side seam opening and grab the shoulder area of the outer vest. Pull gently and steadily until the entire vest turns right-side-out. This takes patience; go slowly so you don't tear anything. Once it's turned, poke out the corners at the neckline and armholes with a blunt tool like a chopstick or the eraser end of a pencil.

Press the entire vest, paying special attention to the neckline, armholes, and front edges. A crisp edge here makes the vest look finished. Now close the side seam opening by hand using a ladder stitch (also called an invisible stitch). Thread a needle with thread that matches the outer fabric, knot the end, and hide the knot inside the seam. Bring the needle out through the fold of fabric on one side, cross over to the opposite side, and run the needle through the fold there for about a quarter-inch. Cross back and repeat. Every few stitches, pull the thread gently so the opening closes invisibly. When the opening is closed, knot the thread inside the seam and trim it.

Topstitch the edges for a professional finish

Topstitching is a line of stitching you can see on the outside of the garment, usually about an eighth-inch from the edge. It holds the lining in place and creates a crisp, finished look. Using thread that matches your outer fabric, sew around the neckline, both armholes, and both front edges, staying about an eighth-inch from the edge. Use a straight stitch and backstitch at the start and end.

This step is optional but worth doing—it's what separates a homemade vest from a store-bought one. If your vest has a collar or lapels, topstitch those too. Press the finished vest one more time, and you're done.

Frequently Asked Questions

What if my armholes or neckline don't fit right after I turn the vest?

If they're too tight, you may have sewn with too narrow a seam allowance. If they're too loose, your seam allowance was too wide. You can unpick the seam with a seam ripper and resew it, or you can adjust the fit by taking in the side seams slightly. Try the vest on before you close the side seam opening—this is your final note to make changes easily.

Can I use a stretchy fabric like knit for the lining?

Knit lining will stretch and shift inside the vest, making it uncomfortable to wear. Stick with woven lining fabrics like cotton or rayon. They're stable, smooth, and designed for this purpose.

What happens if I accidentally sew the side seam opening closed?

Use a seam ripper to carefully cut and remove the stitches along that seam until you have an opening large enough to turn the vest through. Then proceed as normal. It's frustrating but fixable.

Do I need to add interfacing to a lined vest?

If your pattern calls for interfacing at the neckline or front edges, add it to the outer fabric before you sew the pieces together. Interfacing stabilizes these areas so they don't stretch out. Follow your pattern's instructions for where to place it.
