Update: I goofed on the yardage! Updated values include the waistband.
I took the pattern for this knit skirt from a yoga skirt I own. The pattern and construction are very easy and flattering. It doesn't have the beautiful drape of Tanit-Isis's gored knit skirt but the economical cut allowed me to sew a camisole from the leftovers :)
Depending on the degree of stretch in your fabric, desired fit, and your measurements, these dimensions can be changed. I'm waist 71cm, hip 95cm.
Seam allowances of 1.25cm (1/2") and hem allowances of 2.25cm are included.
Fabric: 0.9m/1yd, 120cm/48"+ wide knit
A lightweight jersey with lycra is ideal; to reduce curling don't prewash.
Cut all pieces with the greatest degree of stretch horizontally (around your body).
Waistband: Cut one piece 30cm x 78cm, or two pieces 30 x 40cm and 30 x 41cm
Skirt: Cut two trapezoids as shown below. I cut the back piece upside down since my print isn't directional. Your yardage will differ if cutting both skirt pieces right side up.
*If your fabric is wide enough cut each half of the waistband from the triangular areas top left and bottom right in the diagram. This will reduce the yardage to 0.6m/yd and make the Earth happy :)
Assembly: Using a narrow zig zag or serger, sew the short ends of the waistband right sides together. Press open, fold in half lengthwise wrong sides together and press. The waistband will be worn folded over.
Sew the skirt side seams. Sew the folded waistband to the skirt's top edge, pinning and matching by quarters to ensure even distribution. If you cut the waistband in one piece place that seam at center back. Otherwise sew a piece of ribbon or a label to mark CB. Press all seam allowances toward the skirt and topstitch.
Try on the skirt to check hem length and evenness. Trim as needed and serge the hem if desired. Turn up 2-2.5cm and stitch close to the raw edge. I used a 3mm long x 2mm wide zig zag; a twin needle or coverstitch would also work well.
