Transfer all markings carefully to the wrong side of the fabric before beginning construction.
Cutting Layout
Arrange the pattern pieces according to the cutting layout diagrams provided in the sewing guide, ensuring every grainline runs parallel to the fabric selvage.
The layouts are designed for both 45-inch and 60-inch fabric widths and are intended for non-directional fabrics. If your fabric has a directional print or nap, purchase additional fabric to accommodate the layout.
The illustrated cutting layouts use US Size 40 as the example.
Fabric Cutting and Preparation
Arrange the pattern pieces according to the cutting layout diagrams before pinning them securely to the fabric. Ensure each grainline arrow runs parallel to the selvage.
If using fabric shears, trace the pattern pieces before cutting. Cut carefully, removing any pen, pencil, or chalk lines as you go, and remember to cut all notches since they help align the pieces accurately during construction.
Transfer all pattern markings—including circles, buttonholes, fold lines, and center front markings—to the wrong side of the fabric using chalk, a marking pencil, or a fabric marker.
Seam Allowance
Please follow the seam allowances as indicated on the pattern file layers. These are provided specifically for each piece to ensure accurate construction.
This pattern uses a 1 cm (3/8") seam allowance all around, 1.5 cm (5/8") at the hem, 3.5 cm (3/8") at the placket and, 1.25 cm (1/2") at the side seam, collar and collar stand all around.
Step-by-Step Sewing Instructions
Before you begin:
- Pinning the pieces before sewing is always helpful.
- It is recommended to iron the pattern pieces after every step for a better sewing experience.
1. Finish the Front Plackets
Tip: You can use interfacing to make the plackets stiffer. Use the ready pattern pieces to cut the interfacing.
1a. Fold the placket from the center front toward the wrong side of the front piece.
1b. Trim the excess seam allowance to approximately 1 cm so it aligns with the front placket and reduces bulk. Fold the seam allowance to hide the raw edges toward the wrong side and align it with the front placket. Sew along the placket seamline.
Repeat the same process for the opposite front placket.
2. Attach the Back Yoke
2a. Position both back yoke pieces with their right sides facing each other and sandwich the back piece between them. Align and pin the back across seam.
2b. Sew all three layers together along the back across seam.
3. Join the Shoulder Seams
3a. Fold and press the shoulder seam allowance of both back yoke pieces toward the wrong side.
3b. Insert the shoulder seam allowance of the front piece between the two back yoke shoulder edges and align the shoulder seamlines.
3c. Sew along the shoulder seamline.
Repeat the same process for the opposite shoulder.
4. Prepare and Attach the Collar
4a. Sew both collar pieces right sides together, starting from one corner of the collar stand seam allowance to the opposite corner.
4b. Clip the collar corners, turn the collar right side out, and use a pencil or another pointed tool to shape the collar points.
4c. Take one collar stand piece, fold and press the neckline seam allowance toward the wrong side, then secure it temporarily with basting stitches.
4d. Place both collar stand pieces right sides together with the collar sandwiched between them. Sew along the collar stand seamline, joining both collar stand pieces.
4e. Turn the collar stand right side out and press along the stitch line to create a stable collar shape.
4f. Place the collar stand with the unfolded seam allowance onto the shirt neckline, right sides together. Pin in place and sew along the neckline, leaving the opposite collar stand unstitched.
4g. Sandwich the neckline seam allowances between both collar stands. Remove the basting stitches from the folded collar stand, cover the neckline seam allowance with the folded edge, pin if needed, and sew to give the neckline a clean finish.
5. Attach the Sleeves
5a. Match the center notch of the sleeve with the shoulder seam of the shirt and align the back armhole notches.
5b. Place the sleeve onto the armhole with right sides together and sew along the armhole seam.
Repeat the same process for the opposite sleeve.
6. Attach the Sleeve Plackets
6a. Place the sleeve bind on the sleeve placket marking closest to the back armhole notch. Position the sleeve placket on the opposite side of the placket marking, ensuring the right side of the placket faces the wrong side of the sleeve. Pin the pieces in place and sew along the placket marking.
6b. Cut an opening down the center of the placket marking and make small V-shaped cuts at both ends of the opening.
6c. Turn the sleeve placket pieces through the opening to the right side of the sleeve and press them flat.
6d. Fold the seam allowance of the sleeve bind twice to enclose the raw edges, then sew it in place. Trim the excess to align with the hem if needed.
6e. Fold the seam allowance of the sleeve placket, then fold it again along the center. Adjust it to cover the sleeve placket beneath and pin it in place. Fold the top of the placket over the raw edges, then sew from the bottom edge to the top, creating an inverted V-shaped stitch at the top to secure both sides of the placket.
Repeat the same process for the opposite sleeve placket.
7. Sew the Side Seams
Align the sleeve and side seams where the armhole ends meet. Pin the side seams together and sew continuously from the sleeve cuff to the shirt hem.
8. Attach the Cuffs
Tip: You can use interfacing to make the cuffs stiffer. Use the cuff measurements without seam allowance to cut the interfacing.
Tip: Trim the sides of the cuff to reduce bulkiness.
8a. Fold the seam allowance at the top edge of one cuff piece toward the wrong side and press. Place this cuff piece together with another cuff piece (right sides facing), then sew the sides and bottom edges. Turn the cuff right side out and shape the corners using a pointed tool.
8b. Place the prepared cuff onto the sleeve opening and pin it in place. Sew along the seamline of the unfolded cuff seam allowance.
8c. Turn the cuff down over the sleeve and press.
8d. Tuck the stitched cuff seam allowance inside to cover the cuff seam on the wrong side.
8e. Topstitch along the edge of the cuff to finish.
Repeat the same process for the opposite cuff.
9. Finish the Hem
Fold the hem seam allowance approximately 1 cm and press. Fold the hem again toward the wrong side along the seamline, then sew along the folded edge, starting from one front placket to the other.
10. Sew the Buttonholes and Buttons
Using a buttonhole presser foot, sew evenly spaced buttonholes with zig-zag stitches.
Sew the buttons onto the left front so they align with the buttonholes.
For each sleeve cuff, sew two buttonholes and two buttons:
- One buttonhole and button set should be positioned 1/2 inch away from the cuff side seam.
- The second buttonhole and button should be positioned at the center of the sleeve placket.
