What luxury teams should prioritize

Luxury assortment planning has some unique needs versus mass retail:

• Store differentiation by profile
  Flagships, travel retail, department store concessions, and local boutiques often need very different assortments.

• Curated, limited distribution Planning is less about maximizing volume and more about controlling brand expression and scarcity.

• Omnichannel visibility Online can act as a broader “endless aisle,” but luxury often still protects certain SKUs for flagship or clienteling purposes.

• Clienteling and demand signals Sales associate insights, waitlists, CRM data, and pre-orders can matter a lot.

• Seasonality and drops Luxury often uses collection-based planning rather than continuous replenishment.

• Size/attribute complexity Especially important in apparel, footwear, and accessories.
