Sailor Collar

Materials needed:

  • 1/2 yd of matte bridal satin (online satin source: Online Fabric Store)
  • 1/2 yd of light to mid-weight fusible interfacing (optional, but very useful!)
  • White thread
  • Thread to match your satin
  • Wondertape
  • Pre-made double fold bias tape. We use extra wide for single stripes (Supers and Venus) and 1/4″ wide bias tape for classic senshi with multiple stripes.
  • Iron
  • Tailor’s chalk or fabric pen
  • Ruler
  • Collar pattern piece 


Cut 2 pieces of your collar out of your bridal matte satin and 1 piece of interfacing. For your top layer, grab your interfacing and press it onto the wrong side of your fabric, making sure it’s clean of wrinkles. 



From here, it’s time to mark where you want your stripes to go. We use a half inch seam allowance for our collars and normally set the outside edge of our stripes at 3/4″ in from the seam allowance, so we mark at 1.25″ (1/2″ + 3/4″) away from the edge on the right side of the fabric.


Next, grab your Wonder Tape as well as your double fold bias tape. Wonder Tape is a water soluble tape that is used to hold fabric together as you stitch. Place it on the bottom of your bias tape and place it on  your collar, right along the edge of the line you marked earlier, making sure distances between stripes are consistent and allowing for outside seam allowance on the edge of the collar. We find it best to Wonder Tape one stripe, add the bias tape, mark the next stripe, and repeat the process as many times as necessary for your senshi.


Tip: Be sure not to pull your bias tape as you place it on the collar, as this will lead to wrinkles while you sew.



Once you’ve placed all of your stripes, edgestitch your bias tape and press to help smooth any puckers that may have occurred while sewing.


Grab your other collar piece. With right sides together, stitch both pieces using a ½” seam allowance. Make sure to leave a gap at the center of the neck to flip inside out.


Clip the corners to reduce bulk, being careful not to cut through your stitching. 


Clip your curves to help the fabric lay flat. Once your curves are clipped and corners cut and graded, trim down your seam allowance to reduce bulk.


Flip your collar inside out. Using a chopstick or other pointed object, gently push out the corners and press. 


To finish the neck opening, hand stitch or topstitch the free ends closed. We normally hand finish collars for short-haired characters or characters with exposed necks (e.g., Uranus, Saturn, Mercury, Chibi Moon and Moon). Longer haired characters cover the collar opening, so the topstitching is concealed by the wigs.
