The women’s vest made with pattern 3070 is a clean yet expressive sleeveless design that pairs well with both casual and dressier outfits. The vest is designed for sizes 42–62.
The sample is sewn from boho-style linen, but the pattern also works well with a variety of medium-weight suiting and suit-coat fabrics. The model is made fully lined, features princess seams and a waist dart on the front, a decorative welt pocket (fake pocket) in a frame, a button-front closure at the center front, and a back belt that subtly emphasizes the waist.
This master class is created specifically for pattern 3070 “women’s vest” and will help you achieve a neat fit, a clean welt pocket finish, and a professional join between the outer fabric and lining.
For sewing the vest, it is recommended to use:
Approximate fabric requirements for pattern 3070 women’s vest are shown in the table below (fabric width – 1.5 m):
| Materials | 42 | 44 | 46 | 48 | 50 | 52 | 54 | 56 | 58 | 60 | 62 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Main fabric (1.5 m width) | 0.9* | 0.9* | 0.9* | 0.9* | 1.1* | 1.1* | 1.1* | 1.2* | 1.2* | 1.2* | 1.30* |
| Interfacing (1.5 m width) | 0.8* | 0.8* | 0.85* | 0.85* | 0.9* | 0.95* | 1.0* | 1.0* | 1.05* | 1.1* | 1.5* |

* The stated consumption does not include possible fabric shrinkage, the direction of the print or nap, plaid/stripe matching, fabric skew, or additional technical allowances.
Before cutting, be sure to pre-shrink (decatize) the fabric (steam/press, then allow it to dry and rest), check for defects, and note the nap and print direction.
Using the pattern pieces, transfer all notches and markings to the fabric: darts, princess seams, pocket opening line, waistline, and belt placement. It can be convenient to trace the front and front side panel pieces first (clearly drawing the outlines) and then cut them from the main fabric.
Next, fuse interfacing according to the pattern’s fusing plan: fuse the front edges, parts of the front and back in the neckline area, shoulder areas, parts of the princess seams, and the belt pieces. Stabilize the armholes, front edge, and the front and back necklines with bias stay tape or straight-grain tape; clip the tape/interfacing in curves so it lies smoothly without puckers.
Step 1. Cutting and fusing
Cut all outer fabric pieces and lining pieces, considering grain direction and print placement. Cut interfacing pieces using the corresponding pattern pieces—for the fronts, parts of the front and back, the belt, pocket welts, and facings. Fuse according to the fusing plan: fronts, neckline edges, parts of the princess seams, the belt, and stabilize armholes, shoulder seams, and the lower edge of the front with bias stay tape or straight-grain tape, clipping the interfacing/tape at curves. Lightly shrink the front neckline area with steam before fusing so it conforms better to the neck.
Step 2. Front: dart, princess seam, and pocket opening preparation
Mark the bust/waist dart and the pocket opening line on the front piece. Cut along the marked pocket opening line, extending the cut about 1 cm toward the dart outline. Fold the front right sides together along the dart line, stitch the dart with a 1 cm seam allowance exactly along the marked line, then press the allowances open; trim if needed to reduce bulk.
Baste the pocket opening cut edges “edge to edge” so the cut closes neatly—this temporarily stabilizes the opening before the welt is made. Place the front side panel right sides together with the front and stitch the princess seam with a 1 cm seam allowance, matching all notches. Press the seam allowances open.
Step 3. Making the belt
Place the belt pieces right sides together. Stitch along the two long edges and one short edge, leaving one short edge open. Seam allowance is 1 cm. Trim seam allowances to 0.5 cm at corners, turn right side out, carefully shape the corners, and press. Optionally topstitch around the belt edges at 0.1–0.2 cm.
Step 4. Back and attaching the belt
Place the center back pieces right sides together and stitch the center back seam with a 1 cm seam allowance. Press the seam allowances open. Below the notch on the princess seam edge of the center back, pin the belt so its ends sit on both sides of the princess seams.
Place the back side panel right sides together with the center back and stitch the princess seam with a 1 cm seam allowance, matching notches and catching the belt in place. Press the princess seam allowances open. Stabilize the back armhole with stay tape, clipping the tape at curves so it lies flat.
Step 5. Decorative welt (fake) pocket and side seams
On the front, extend the pocket opening line from the dart toward the front edge by about 1.5 cm and draw a vertical line through this point. Measure 11–14 cm (depending on size) from it and make a second reference mark—draw another vertical line through that point. From the main pocket opening line, mark 0.5 cm up and 0.5 cm down and draw parallel lines, extending them slightly beyond the future frame. This creates the pocket frame rectangle.
Fuse the welt pieces (upper and lower), fold each in half lengthwise with the fold to the outside, and press. Sew a guide stitch 0.5 cm from the fold—this will be your alignment line.
Place the upper welt on the upper marked line so the guide stitch matches the marked line, with the folded edge pointing upward (toward the neckline). Stitch exactly along the guide stitch from corner to corner, backstitching at the ends. Then fold the seam allowance away from the upper welt.
Place the lower welt on the lower marked line with the folded edge pointing downward and stitch the same way. From the wrong side of the front, slash the pocket opening along the center line, stopping about 1.0–1.5 cm before each end, then clip diagonally into the corners, stopping about 0.1 cm before the stitching.
Pull the seam allowances and welts through to the wrong side, shaping a neat rectangle. Square up the corners, then stitch the little corner triangles down onto the welt seam allowances to secure them. From the right side, bring the two welts together “edge to edge” and secure with hand stitches. Press the welt frame.
Place the pocket facing from the wrong side, align edges, and stitch it to the welt seam allowances around the perimeter. Finish the raw edges of the facing. Remove any temporary basting and press the pocket area again. Then stitch the side seams of the outer vest right sides together with a 1 cm seam allowance, matching notches; press seam allowances open.
Step 6. Lining and facings
On the front lining, mark and form the pleat (or tuck) according to the pattern, matching notches; secure it with a seam and press toward the center. Place the front facing (front edges and part of the neckline) right sides together with the front lining and stitch along the front edge and neckline with a 1 cm seam allowance, matching notches. Press the seam allowances toward the lining.
Place the upper back facing and the lower back facing right sides together with the corresponding edges of the back lining and stitch with a 1 cm seam allowance, matching notches. Press the seam allowances toward the lining.
Next, place the front lining and back lining right sides together and stitch the side seams with a 1 cm seam allowance, matching the seams where facings are attached. Leave a turning opening about 10–12 cm long in the left side seam: first stitch that section with a long stitch length, press the seam open, then unpick only the long-stitch section. Press the side seam allowances toward the back.
Step 7. Joining outer vest and lining at front edges, neckline, and hem
Lightly steam-shrink the front neckline facing to remove any excess length. Place the outer vest and lining right sides together. Stitch along the front edges, front neckline, and hem with a 1 cm seam allowance, aligning edges and matching notches. Start and finish the stitching about 5 cm below the shoulder seams, leaving the shoulder areas open.
Trim seam allowances along the front edges, neckline, and hem to 0.3–0.5 cm; trim bulk at corners. Turn the vest right side out through the lining opening, carefully shape the corners. Baste the seams along the edges, neckline, and hem, creating a slight roll of the main fabric (0.2–0.3 cm) toward the lining. Press from the wrong side, remove basting, then lightly press the edges from the right side.
Step 8. Finishing armholes, shoulder seams, and closing the turning opening
Check armholes for symmetry and align the lining and outer edges. With lining and outer vest right sides together at the armholes, stitch around each armhole with a 0.5 cm seam allowance, starting and ending about 5 cm below the shoulder seams. Form a slight roll of the main fabric toward the facing. Turn right side out and press the armholes with the roll.
Check shoulder seam lengths: the lining/facing shoulder should be about 1 mm shorter than the outer shoulder so the armhole doesn’t gape. Trim if needed. Through the turning opening, pull out the shoulder areas, stitch the outer shoulder seams right sides together with a 1 cm seam allowance, and press seam allowances open. Then stitch the lining shoulder seams the same way with a 1 cm seam allowance.
Through the same opening, stitch the small unsewn sections at the armholes and, if needed, at the neckline near the shoulders so the seam is continuous. Turn the vest right side out and press thoroughly. Close the turning opening in the lining side seam with invisible hand stitches.
Step 9. Buttonholes, buttons, and final pressing
Use the pattern to mark buttonhole and button placement along the front edge. Align with the waistline and overall length so the buttons are evenly spaced. Make the buttonholes on the right (or left—your preference) front according to the marks. Sew on 4 buttons on the opposite side, directly across from the buttonholes.
Finally, give the vest a careful press: neckline, front edges, belt area, armholes, and hem. Avoid flattening the rolled edges and avoid pulling the seams. Your pattern 3070 vest is ready for fitting and wear.
