If you know a bit about sewing and stitching then making your own salwaar is not tough. 

You can try it. 

What you need – for an average height and medium waste person:

Material – 2.25 metres of cloth ( it is good to buy cloth that has a good width- 45-48 inches). Cotton/ handloom is preferred for the summer months. 

A pair of scissors 

Needle and Thread that matches the cloth shade 

A sewing machine. 

Step 1.  The total length of this salwaar is 41-42 inches approximately. 

 To make the two legs you need to fold the cloth width wise. The length of the leg from below waist will be around 30-31 inches. In the picture below you will see the cloth folded width wise and doubled. 

Step 2.  Now on the open end you must leave 10 inches straight cloth. Below that you have to cut the cloth tapering down to the feet area. The lower portion will have a width of 8.5-9 inches. Cut the cloth. A black cloth has been cut to show the shape. 
Step 3. The upper waist band is next. It must be 42-46 inches long and 9-10 inches in width. The two legs will be joined to the waist piece. Plus the top most area needs to be folded by an inch for the nada to slip in. 

Other parts required are  the miani or two small triangle pieces of cloth that is stitched on the upper inner leg portion. This will help avoid the leg area tearing. 

The poncha or lower leg area has to be thick. For that you can cut out 4 strips of cloth, an inch width. 


Step 4. The miani has to be cut urebi that is tangent on the cloth. So that it can stretch. 

Step 5. The strips for the poncha or lowest portion of the leg. 

Step 6. Now stitch the inside of the legs. Add the miani as done in picture below. These legs have to be stitched to the waist. 


Step 7. Stitch the waist band. You will notice that the legs are far broader than the waist. The front of the legs have to be gathered little by little and running stitch by hand can be done for neatness. 

Step 8 . Running stitch. Ensure that you have portioned out the front area and back area. 2/3 of the leg area will be stitched in front. 
Step 9 . The back side will have a few gathers only. 
Step 10. Now use your sewing machine over the running stitch. 

Step 11. The salwar is ready 

Step 12. Ready to wear. 

For more gathers or if you want to stitch a patiala salwaar then the width of the cloth has to be increased by adding more cloth length wise.
