Let’s see how to draft the pattern of this mini skirt.
Start from a basic skirt with full front.
On both front and back flare 2-3cm from the side seam to the hip line and square down from the darts.
Cut through these lines.
Close the existing darts and open their volume into these cuts.
Draw the skirt shape and the bottom ruffle.
Mind that you should have two different fronts.
Copy the separate pieces and ruffles and on these ones draw some slash lines evenly spaced.
Cut through the slash lines and open them adding some volume to the ruffle hem.
Copy the pieces, add a waistband long enough to tie it in a bow and your pattern is ready!
