For the flared version of the Arlette, the front and back require alterations.The waistband pattern pieces remain unaltered and the pattern pieces for the flounce are not used.
Follow the steps with/on the illustrations to alter the pattern.
Draw the specified seam allowances around the the new pattern pieces and cut these out.
To sew the skirt, follow the sewing instructions on the Instructions of the Arlette Skirt or see p. 57 on the checklist.
Draw a vertical line starting from under each dart/dart intake point all the way down to the hem of the front and back.
Slash the back pattern by starting at the bottom of the vertical line and working your way up to the dart/dart intake point. Next, starting at the top, slash from 1 dart leg until just before the dart/dart intake point. (Don’t slash all the way through the pattern piece; it should remain attached at the dart point.)
Position the dart legs together: pivot the dart closed.
Measure the new allowance created at the hem (red star).
Now cut the front along the vertical line, starting at the bottom and slashing through the dart/dart intake point to 1 dart leg. Slash all the way through the pattern. You should now have two separate pattern halves.
Position the dart legs together and be sure that the allowance at the hem is identical to that of the red star at the back hem (Don’t forget: the pattern is spread out slightly at the dart point, which is not the case for the back.)
Always take half of this allowance of the red star and add this to the side seams of the front and back.
Draw the new side seams and hemline.
