What does "set-to-set" or "catalog buying" mean in Indian wholesale?

In Indian wholesale (especially Surat), most ready-made garments are sold in "catalog sets" — a fixed collection of pieces, usually all of the same design but in different sizes or color variants.

How it works:

• A catalog is a collection of garments photographed together (typically 6–12 pieces per catalog)
• You buy the full catalog set — you cannot pick individual pieces from it
• "Set-to-set" means you buy one complete set per design at a fixed total price
• The per-piece price multiplied by the number of pieces equals the catalog total

Example: A cotton kurti catalog of 8 pieces priced ₹260 per piece = ₹2,080 for the full catalog set. You receive all 8 pieces — different sizes (S, M, L, XL, XXL, XXXL) or color variants.
