What is a Series and Assortment in Wholesale Clothing? B2B Sizing Guide

Mastering packs, lots, size ratios, and color assortments when buying wholesale ready-to-wear apparel from Istanbul factories.

Understanding 'Series' and 'Packs' in B2B Fashion Wholesale

Unlike retail shopping, wholesale fashion clothing is produced and shipped in fixed bundles called Series, Packs, or Lots. Manufacturers do this to optimize fabric cutting patterns and maintain uniform production standards.

Typical Wholesale Pack Ratio

A standard 4-piece women's dress series typically contains:

  • 1x Small (S)
  • 1x Medium (M)
  • 1x Large (L)
  • 1x Extra Large (XL)

On Merter Vitrini, every product page clearly indicates the exact units per package, weight per item, and price per piece so you can calculate your retail profit margins instantly.
