Let's draft together the pattern for these statement shorts.
You need a structured fabric as faille, mikado or gabardine - or a softer fabric with added structure from an interlining.
Start from a basic block, lower and widen the crotch and shorten and widen the leg.
On front, draw the ruffle position and shape.
Trace a copy.
On front draw also the slash line for inserting the ruffle and the pocket.
Trace the front separate pieces:
Add volume to the ruffle by using the slash lines.
Mark the pleats.
Your pattern is ready!
