Capes may have their naysayers, but is there anything more fun to wear than the most iconic of superhero accouterments? This luxuriously swishing rendition is a generous half circle, with stacked box pleats at the shoulders. It’s also kept on with snaps, so you can swiftly detach in the event of an emergency.

Tools and Materials

  • Sewing Essentials
  • Lightweight fabric with a soft drape, such as blouse-weight cotton, silk/cotton blends, silky polyester, charmeuse, crepede chine, or even lining fabric— amount based on step 1
  • 10″ (25.4 cm) of twill tape, ½” to 1″ (1.3 to 2.5 cm) wide (Anything in
    this size range will work.)
  • 1 yd (.9 m) of bias tape, ½” (1.3 cm) single-fold (optional)
  • 6 large sew-on snaps
  • Large safety pins
  • All-purpose thread in a matching color
  • Trim or decorative medallions for the shoulders (optional)

Pattern Pieces

Choose stable fabrics that doesn’t stretch or fray much, and make sure that both the garment you’re attaching the cape to and your chosen fastening method can stand up to the weight of the cape. If you want to use a heavy, bulky fabric like velvet, you may need to reinforce the attachment point with interfacing or a piece of twill tape behind the snap area. If you’re attaching the cape to a stretch garment, stick with very lightweight fabrics for the cape to avoid straining the fabric.


⅜” (1 cm) seam allowances are used for this pattern

Step 1

Begin by determining how much yardage you need to buy for your cape. The amount of fabric required will be twice your finished length + your shoulder width (measured across your back) + 16″ (40.6 cm) for shoulder extensions and hem allowance. Excess width will fall into draped folds down your back, so if you like that look, feel free to exaggerate it by adding even more width to your shoulder width measurement. (Because the pattern is cut on the fold, any adjustment in the measurement should be halved when placing the template.) The maximum cape length will be the width of the fabric minus 9″ (22.9 cm) unless you want to add a seam; for a long cape, make sure you’re buying a sufficiently wide fabric. For this cape, 3½ yds (3.2 m) of 54″- (137 cm-) wide fabric was used, based on a finished length of 45″ (114 cm) and a shoulder width of 16″ (40.6 cm).

Step 2

Fold the fabric along the cross grain, aligning the selvages.
Place the cape template at the top of the folded edge, making sure to place the half-shoulder width mark at the appropriate distance from the fold. (Compare your shoulder width to the bar on the cape template to determine where to place the template on your fabric.)
Use the pleat lines as a guide to extend the cape to the desired length, adding the same amount onto the end of each pleat line and at the center back (A).

Step 3

Connect the marks into a smooth curve to create the hemline of your cape. Cut along the hem curve, around the top edge of the cape template, and parallel to the selvages for the straight front edge (it’s best to trim the selvages off as they’re more tightly woven than the rest of the cape and may pull or ripple). If there is a gap at the center back neckline,
simply cut straight across to the fold. Mark the pleat positions with small snips in the seam allowance.

Step 4

Sew a narrow or double-fold hem on the two straight front edges of the cape. Finish the curved neckline edge with a narrow bias facing, as shown on page 65 (B).
The facing used here is a bias strip cut out of leftover cape fabric that is 1″ (2.5 cm) wide and stitched on with a ⅜” (1 cm) seam allowance.

Step 5

Use the snips you made in step 3 and the center notch as a general guide to form the pleats on each shoulder. Arrange the pleats to your liking and pin in place (C). For example, you may want to make the pleats shallower or deeper to adjust the amount of shoulder coverage. Make sure both sides match.

Step 6

Place a 5″ (12.7 cm) strip of twill tape on top of the end of the pleats on the right side of the fabric as shown in (D). Sew in place along the upper edge of the tape.

Step 7

Wrap the ends of the twill tape around the edges and fold to the underside. Stitch around the edges of the tape through all layers. Attach the male side of the snaps to the twill tape (E) and the female side to the garment. Repeat steps 6 and 7 for the second shoulder.

Step 8

Clip the shoulder pieces to a hanger and let the cape hang for a day or two so the fabric can relax. Pin the cape on a dress form or safety pin it to a helpful friend and check the length. Trim if necessary to make it nice and even and sew a narrow double-fold hem around the long curved edge (F).
If you like, attach trim or decorative medallions to hide the shoulder ends.
