Short answer
A dress material set is usually unstitched fabric for a three-piece outfit: top (kameez) fabric, bottom fabric and a dupatta. The buyer or a tailor stitches it to size.
Sets vary by catalogue, so confirm each component before ordering:
Semi-stitched suits have the main panels partly stitched for quicker tailoring. Unstitched sets are among Surat's most exported products because they pack flat and fit every body type.
