Choose a saree with enough fabric, preferably silk, georgette, chiffon, or crepe
Measure your waist, hip, and desired lehenga length
Unstitch the saree carefully if needed
Keep the border and pallu aside for decoration
Cut the main fabric into panels for the lehenga flare
Add lining fabric if the saree material is thin or sheer
Stitch the panels together to form a circular or semi-circular skirt
Add gathers or pleats at the waist for volume
Attach a waistband with hooks, zip, or drawstring
Use the saree border to finish the hemline
Use the pallu as a dupatta or decorative panel
Add can-can or stiffening fabric if you want extra flare
Try the lehenga on and adjust the fit
Finish all seams neatly and press the lehenga
Decorate with embroidery, lace, or embellishments if desired
