Measurement
Items Per Session
Items per session is the average number of distinct products added to the cart or purchased in a single shopping session — a direct measure of cross-sell effectiveness and outfit-buying behavior.
What this means
Items per session is one of the clearest signals of whether a shopping experience is driving multi-item purchases or single-item transactions. A store where shoppers consistently buy one item at a time has different growth economics than one where multi-item baskets are common. Outfit-based selling directly targets this metric: by presenting multiple coherent pieces as a single decision, it makes buying several items feel like one purchase decision rather than several separate ones.
Why it matters for fashion brands
Elara deployments show 2.4x items per session for outfit-engaged shoppers versus individual product browsers. Outfit assembly drives items-per-session because a complete look recommendation presents multiple pieces as a coherent decision, making it easy for the shopper to buy several at once.
