No Pattern Needed: Side Split Cap Sleeve Top

Supplies Needed:

  • 1 yard woven fabric
  • Tape Measure
  • Thread
  • French Curve or French Curve Ruler Template


  1. Print off the French Curve Ruler found here if you dont have one. You will download it just like any other pdf pattern. You can paste it to poster board if you would like it to be more sturdy or you plan to use it again.
  2. Measure your chest and divide by 2 then add 10.
    • Example: Chest measurement- 34/2=16+10=26 measurement A
  3. Cut 2 rectangles= Measurement A x 25 inches (length of shirt)- One for the front and one for the back.
  4. Using the french curve, trace armhole, bottom, and neck. then Cut.
  1. Reference the below list for common measurements using the french curve. The measurements to trace will be from Number to number- Only trace the curve in that area.
    • Armhole curve: From 6” to 17”
    • Hip curve: From 0 to 9”
    • Front neckline: from 16” to 11”
    • Back neckline: from 15 1/2” to 12”
  2. Using a rolled hem, fold and press bottom of both front and back bodice pieces in ¼ inch, then fold in ½ inch, then sew.

7. Repeat for the neckline and armholes on the front and the back piece.

8. Sew shoulder seams together with 1/2 inch seam allowance, Finish your seams with your prefered finishing technique.

9. Cut out cap sleeves- Lay your Shirt open like the photo. Trace the curved opening labeled A onto your fabric. Then connect the two ends to make your cap sleeve. I measured out from the shoulder seam 2.5 inches, then hemmed the straight egdge using the same rolled hem method.

10. Lay shirt face open and place sleeve underneath, matching the center of the sleeve with the center of the shoulder seam, pin and sew in place. Trim excess with pinking shears.

11. Overlap the side pieces with the front piece on top.  Pin and try on to make sure you have the proper fit. Once you have the correct fit, stitch the pieces together .

And thats a wrap!
