The women’s jacket made with pattern 3213 is a classic straight-cut denim jacket with a moderate fit, designed for heights of 164–172 cm. The model features a dropped shoulder line and a two-piece sleeve with a cuff, which gives the silhouette a modern look while remaining comfortable to wear.
The front includes a yoke with a flap pocket; the neckline features a stand-and-fall collar; and the hem is finished with a continuous band (hem cuff). The jacket closes with snaps, and adjustable tabs are placed at the back hem to slightly regulate the hip circumference.
This tutorial is suitable for sewing the jacket using pattern 3213 in all sizes listed in the consumption table.
For sewing the jacket using pattern 3213, the following are recommended:
Below are approximate material requirements for pattern 3213 in different sizes.

* material consumption is given without allowances for shrinkage, skewing, gaps, and other technological losses;
** the length of elastic tape (if additionally used) is approximate and depends on the density and stretch of the elastic.
Before cutting, be sure to pre-shrink (decate) the main fabric and lining, and check them for shrinkage, colorfastness, nap direction, and print direction. Press the fabric thoroughly and let it “rest.”
Cut the jacket pieces from the main fabric, lining, and interfacing according to the pattern 3213 templates, observing the grainline direction and all notches. Be sure to transfer all control marks to the fabric: pocket opening lines, flap placement, back pleats, tabs, and snap positions.
Apply interfacing according to the interfacing plan included with the pattern. Typically, interfacing is applied to the pocket opening on the front piece, one pocket flap, one collar stand piece and the upper collar, the front plackets, neckline areas, and the snap reinforcement areas on cuffs and tabs.
Step 1. Back and yokes
Place the back yoke and the lower back right sides together, matching the notches. Stitch the yoke with a 1 cm seam allowance, finish the seam allowances, and press them toward the yoke. Topstitch the yoke with double stitching: the first line about 0.1 cm from the joining seam, the second line about 0.5 cm from the first.
Next, join the front yokes to the back at the shoulder seams, right sides together. Stitch the shoulder seams with a 1 cm seam allowance, finish the seam allowances, and press them toward the back yoke. Make double topstitching along the shoulder seams, keeping the original uneven shoulder line shape—do not try to “straighten” it with the iron.
Step 2. Front pocket opening
On the front piece, mark the pocket opening fold line using the pattern. Interface this area with the special fusible piece from the pattern set, fusing only the fold section. Press the pocket opening fold along the notches and finish the raw edge.
Measure 3 cm from the fold line and sew double topstitching along the pocket opening. These stitches secure the fold and create a neat pocket edge.
Step 3. Front side piece lining and pocket formation
Place the lining (pocket bag) piece onto the front side piece right sides together, aligning the edges. Stitch, finish the seam allowances, and press toward the lining.
Using the notches along the pocket opening line as a guide, place the front piece and the side piece right sides together, match the notches, and align the edges. From the wrong side, check that the lining edge falls slightly short of the raw edge—this area will later be covered by the placket. Secure the lining with basting stitches along two adjacent edges, forming a soft inner pocket.
Step 4. Making the pocket flaps
Cut four identical flap pieces. Interface one pair (the outer/upper flaps), especially if the denim or other main fabric does not hold its shape well or if snaps will be installed.
Pair the flap pieces right sides together and stitch around three sides with a 1 cm seam allowance, leaving the top edge open. Trim the seam allowances at the corners at a 45° angle, being careful not to cut the stitches. Slightly notch the seam allowances in the center of the lower edge (about 0.4–0.5 cm) to reduce bulk.
Turn the flaps right side out, shape the corners, and press them “on the edge” without a pronounced turn of cloth. For convenience, you can draw a helper line at 45° to the flap edges. Sew double topstitching around the flap perimeter.
Step 5. Attaching the flap and installing snaps on the lower front
On the lower front piece, find the flap placement notches from the pattern and match them to the marks on the flap. Secure the flap by stitching it to the lower front, then fold it down and press.
At this stage, mark and install the main snaps, following the outlines provided on the pattern pieces. Mark the snap positions and install the socket/cap part through the lower front piece.
Then install the corresponding snap part on the flap so that, when fastened, the flap holds firmly over the pocket opening fold. Make sure the flap covers the pocket symmetrically. Add extra stitching to secure the lower front and the side piece together to prevent the lining from shifting during wear.
Step 6. Joining the lower front with the insert and yoke
Place the lower front and the front insert right sides together, matching the notches and edges. Stitch with a 1 cm seam allowance, finish the seam allowances, and press them upward. From the right side, sew double topstitching along the joining seam to secure the seam allowances.
Place the assembled lower front (with pocket, flap, and insert) to the front yoke right sides together, matching the notches. Stitch with a 1 cm seam allowance, finish the seam allowances, and press them toward the yoke. Sew double topstitching along the yoke seam to secure the seam allowances and emphasize the design line.
Step 7. Back pleats
On the lower back piece, mark the pleat positions using the notches on the pattern. Fold the pleats toward the center back, matching the marks. Secure the pleats with a short machine stitch along the top edge of the piece, directing the pleat allowances toward the center. Press carefully, keeping a soft volume in the pleats.
Step 8. Sleeve vent preparation and elbow seam
On the upper sleeve piece at the vent area near the hem, turn the edge 0.3–0.5 cm to the wrong side and stitch to hold the allowance. Near the notch, taper the allowance smoothly to “zero” to avoid bulk.
Place the upper and under sleeve pieces right sides together and match the notches along the elbow and front seams. Stitch the elbow seam from the sleeve cap down to the vent notch with a 1 cm seam allowance. Finish the seam allowances. When finishing the vent, first finish the section on the upper sleeve separately, then finish the raw edges of both sleeve pieces together.
Step 9. Sleeve topstitching and hem pleats
Press the elbow seam allowances toward the upper sleeve. From the right side, sew double topstitching along the upper sleeve to secure the seam allowances: the first line about 0.1 cm from the seam, the second about 0.5 cm from the first. Stop the stitching about 1 cm before the vent notch.
At the hem of the upper sleeve piece, form two pleats directed toward the vent. Match the notches from the pattern and secure the pleats with machine stitching. Direct the pleat allowances toward the sleeve vent. Prepare the second sleeve the same way.
Step 10. Setting in the sleeves and sewing the side seams
Insert the sleeve into the armhole with right sides together. Match the yoke notch to the corresponding notch on the sleeve cap, align the sleeve-cap center notch with the shoulder seam, and match the yoke seams to the under-sleeve seams.
Set the sleeve with a 1 cm seam allowance, distributing the ease evenly. Finish the seam allowances and press. From the right side, sew topstitching along the armhole line to secure the seam allowances on the front and back.
Place the front and back right sides together, match the side seams and sleeve seam. Stitch the side seam and the underarm sleeve seam in one continuous seam. Finish the seam allowances and press them toward the back.
Step 11. Sewing the collar with stand
Prepare the collar pieces: interface one upper collar piece and one stand piece; leave the second stand and the under collar without interfacing. Place the stand and collar right sides together along the lower edge of the collar, aligning the center notch, and stitch with a 1 cm seam allowance.
Press the seam allowances open to opposite sides and secure with topstitching on both sides of the seam: stitch about 0.1 cm from the seam on the collar side and on the stand side. Next, place the upper and under collar right sides together; the upper collar should be slightly larger around the perimeter to form the turn of cloth. Stitch the collar along the top edge and outer edge with a 1 cm seam allowance, stopping about 1 cm before the lower edge of the stand. Trim the corners, turn the collar right side out, shape the corners, baste, and press with a slight turn toward the under collar. Optionally, topstitch along the collar edge.
Step 12. Attaching the collar to the neckline
Place the lower stand piece with the assembled collar to the garment neckline right sides together. Match the back center notch to the stand center, and the stand end notches to the front center notches. Stitch the collar into the neckline with a 1 cm seam allowance, finish the seam allowances, and press toward the stand.
If needed, sew topstitching from the right side along the collar attachment seam, securing the seam allowances toward the stand.
Step 13. Front plackets
Interface the plackets in advance. On one long side of each placket, press the seam allowance to the wrong side. Place one placket and the garment front edge right sides together, align the neckline and hem edges, match the front center notch to the notch on the stand, and stitch the placket along the top edge and the front edge with a 1 cm seam allowance.
Trim the seam allowances at the upper corner, turn the placket right side out, shape the corners carefully, baste, and press with a slight turn toward the front edge or press “on the edge.” Topstitch along the placket edge about 0.1 cm from the edge; optionally, add a second parallel line closer to the fold of the front edge.
Attach the second placket on the opposite side in the same way. The pressed inner edge should cover the attachment seam and the neckline seam with the stand; secure it with blind hand stitches or by machine stitching “in the ditch.”
Step 14. Sleeve cuffs
Fold the cuff pieces in half lengthwise with wrong sides together and press. Reinforce the snap areas with small squares of fusible interfacing. On the inside of the cuff, secure the seam allowance on one long edge with a basting stitch about 0.5 cm from the edge.
Place the cuff right side to the wrong side of the sleeve, aligning the cuff edges with the sleeve vent edges and matching the lower edges. Stitch the cuff to the sleeve hem with a 1 cm seam allowance. Turn the sleeve, fold the cuff to the right side, and tuck the seam allowance inside the cuff.
Place the pressed inner cuff edge over the attachment seam, align, and pin. Topstitch around the cuff (along the outer edge and the lower edge), securing the inner edge and covering the attachment seam.
Step 15. Hem band (hem cuff)
Prepare the hem band pieces using the same method as for sleeve cuffs: fold in half, reinforce snap areas, and secure one long edge with a basting stitch. Place the band right side to the wrong side of the jacket hem, matching the band center to the back center and the band side seams to the garment side seams.
Stitch the band to the jacket hem with a 1 cm seam allowance. Fold the band to the right side, tucking the seam allowance inside. Place the pressed inner edge over the seam, align, and secure. Topstitch around the band perimeter, securing the inner edge and creating an even hem line.
Step 16. Making and attaching the back tabs
Place the tab pieces right sides together and stitch around the perimeter with a 1 cm seam allowance, leaving one short edge open. Trim the corners, turn the tab right side out, and shape the corners. Press and topstitch along the edge at 0.1–0.2 cm; optionally add a second parallel line.
The tabs are attached after the jacket is fully assembled. Using the side seams and pattern marks as a guide, place the tab on the hem band so that the open edge sits right next to the side seam and the free end points toward the front. Stitch the tab in place with a seam about 0.5 cm.
Fold the tab toward the back and topstitch it onto the hem band, continuing the side seam line. Provide two snap positions on the tab so the hip circumference can be adjusted.
Step 17. Installing snaps
Using the pattern and the transferred markings, mark the snap positions on the pocket flaps, front plackets, sleeve cuffs, hem band, and tabs. First install the snaps on the pocket flaps and the lower front piece—check that the flap presses the pocket opening firmly.
Next install the row of snaps on the front plackets: the first near the neckline, the last above the hem band, and distribute the rest evenly. When fastened, the front edges should not twist. Install one snap on each sleeve cuff to secure the vent. Place two snaps on each hem tab to adjust the fit: a base position and a tighter position.
Step 18. Final pressing
Do the final pressing: press the yokes, front and back joining seams, armholes, collar with stand, plackets, cuffs, and tabs thoroughly. Create crisp edges along the topstitching lines, making sure not to distort the silhouette or stretch the front edges.
Check the symmetry of the pleats on the back and sleeves, and the evenness of the hem and sleeve hems. Fasten all snaps and make sure the closure works smoothly, the front edges do not gape, and nothing is pulled off-grain. The jacket made with pattern 3213 is ready for fitting and wearing.
