1 Draft a pattern onto paper using the diagram at sewmag.co.uk, then follow the cutting guide. Stitch the grey strip to the centre of two pink rectangles, press the seams open, then fold the piece in half through the grey. Position the pattern on the fold, then cut out the front outer piece. Match, pin and stitch the shoulder seams of the pink front piece to the back, right sides facing. Press the seam allowances open.

2 Pair together, then pin and stitch the shoulder seams of the grey front part to the back, wrong sides facing. Press the seam allowances open. Pair the neckline and armholes together, with pink, right sides facing, and grey, wrong sides facing.

3 Pin and stitch around both armholes and the neckline. Clip around the curved seam allowance, then turn right sides out by threading the back top part through the shoulders. Tease out the armhole and neckline seam allowance, then press flat.

4 Couple together the top pink layer side seams, pin and stitch from the base up to the armholes, then continue stitching half way down the side seams of the grey layer. Cut into the seam allowance at the end of the stitching line.

5 Fold the seam edges in the opposite direction and complete the seam to the base of the top. Ensure the armhole seams are open and matching when sewing, then press the seams open. Match together the back seams, then pin and stitch to the notch to create the back opening. Press the seam open.
