Download the template, then print out and follow the cutting guide. Apply fusible interfacing to the wrong side of the front facing and the back neck facing. Sew the facings together at the shoulder seam and press open. Finish the outside edge of the facing with an overlocker, or turn and stitch a narrow hem. Mark the placement position of the casing on the front and back pieces using tailor’s chalk or a fabric marker pen. With right sides together, pin and sew the centre back seam. Trim the seam and neaten the edge, then press.
Pin and sew the centre front seam to the marked dot, right sides together. Trim and neaten the seam edge, then press. With right sides together, pin and sew the front and back at the shoulder. Trim and neaten the seam edge, then press. Pin and sew the centre front seam to the marked dot, right sides together. Cut and neaten the seam edge, then press.
With right sides together and matching up the centre back and the notches, pin and sew the facing to the neck edge on the front and back. End the stitching at the marked dot on the front of the jumpsuit. Sew across the end of the front facing, trim the seam and press. Cut the seam and snip the curved edge of the back neck facing. Understitch the facing and press towards the wrong side of the jumpsuit. Sew the end of the front facing in place over the centre front seam.
Overlap the front and mark, then sew the buttonholes on the front facing. Secure the buttons, checking that the front facing stays flat when fastened. With right sides together and matching up the notches, stitch the pockets into position on the side edge of the front and back using a narrow seam. Neaten the seam edge, then press the pocket seam away from the jumpsuit. Pin the front and back together at the side seam from the underarm to the start of the pocket, then around the pocket and down to the hem.
Stitch from the underarm to the top of the pocket, then sew past it by 1.5cm. Sew around the pocket, then stitch 1.5cm above the top to the hem. To allow the pocket to fold towards the front smoothly, clip from the edge to the side seam stitching. Trim and neaten the edge, then press. Fold the pocket towards the front and press into position. With right sides together, matching up the notches and aligning the centre front and back seams, pin and sew the inside leg seam. Trim and neaten the seam edge, then press.
Try on the jumpsuit and check that the placement of the elastic casing is right for you. Press the casing in half lengthways, open out and press each raw edge to the centre, then pin and sew. The raw ends of the casing should just tuck under the finished edge of the front facing. Measure the right length of elastic for your waist and thread this through the casing. Tuck the ends of the elastic and the casing under the edge of the front facing and sew in place.
Stitch a press stud inside the facing at the point where the elastic and the facing meet; this will prevent the elastic pulling it open. Finish the edge of the capped sleeves with a narrow hem, then check the length of the jumpsuit and hem the legs to finish.
