How lululemon's inventory choices shape guest experience and margins

Empty hooks and missing sizes at lululemon often reflect decisions made long before a product reached the floor. Inventory is the company’s biggest investment and its biggest risk, so the way product is allocated, timed, and replenished shapes both the guest experience and the margin you are working to protect.

Why inventory scarcity is often deliberate

In retail, inventory is not just product; it is cash tied up in the business. The National Retail Federation recommends open-to-buy planning, category-level spending decisions, careful control of SKU counts, and keeping 10 to 15 percent of the budget open for in-season trends or replenishment.

That is why a style can vanish quickly without it being a simple mistake. A missing size may reflect a deliberate allocation choice, a regional demand read, or a decision to preserve margin by avoiding overbuying. In a premium brand like lululemon, the floor assortment guests see is the end point of financial and merchandising calls made well before the first unit is hung.

How size curves shape what guests see

Size curves are where inventory strategy becomes visible to the guest and to the educator explaining the gap. A strong curve is not about filling every store with the same depth in every size; it is about matching unit mix to what actually moves in that market. That is why some sizes are protected and others sell through fast.

For store teams, this is where the conversation gets practical. When a guest asks why a favorite legging is gone in one size but still available in another, the answer is often tied to allocation, not neglect. The product may have been concentrated in the sizes and regions where sell-through was strongest, while slower sizes were kept lighter to reduce the risk of markdowns later.

That approach helps explain why certain styles seem to arrive in waves. Replenishment is not always immediate, and not every item is built to be chased endlessly. The mix you inherit on the floor is often the result of a planned first order, a forecasted follow-up, and a deliberate decision about how much risk the company is willing to hold in each size and color.

Replenishment timing is a profit decision, not just an operations task

Planning ahead reduces stockouts, overbuys, and last-minute discounts. In apparel, excess units can quickly turn into markdowns that damage margin and train guests to wait for a sale. Better forecasting and pre-orders are meant to prevent that cycle before it starts.

For an educator or assistant store manager, the operational lesson is to watch what is selling, what is sitting, and what needs a second chance on the floor. A style that is moving too quickly may need replenishment urgency, while a style that is lingering may need a different placement or a markdown path. The better the team understands assortment discipline, the easier it is to explain why some products disappear fast while others come in waves.

That also changes how you read guest feedback. A comment about a sold-out color is useful, but it is only one input into a system that is balancing demand, inventory risk, and future margin. Understand whether the system needs more replenishment, tighter allocation, or a cleaner exit from a product that is not working.

Why lululemon’s own numbers make this matter more

lululemon’s filings show how central inventory forecasting is to the business. The company says it must forecast inventory needs and place orders with manufacturers based on estimates of future demand for particular products. It also warns that its ability to forecast accurately can be affected by changes in guest demand, competitor products, and how new product introductions are received.

lululemon said revenue for fiscal 2025 reached $11.1 billion, up 5 percent, with 44 net new company-operated stores and 39,000 employees. The company then ended the first quarter of fiscal 2026 with 816 stores after opening five net new company-operated stores. In that quarter, revenue rose 4 percent to $2.5 billion, comparable sales increased 1 percent, gross margin fell to 54.2 percent, and operating margin fell to 11.2 percent.

North America comparable sales declined 5 percent, while international comparable sales rose 13 percent. Management also said it saw a sequential improvement in full-price sales in North America and was taking additional actions to reposition the business and strengthen the product engine.

What this means for educators and leaders on the floor

The most useful habit for store teams is to treat inventory as a story about decisions, not just availability. When a style sells through, ask whether the issue was a limited allocation, a regional skew, or a forecast that underestimated demand. When a product lingers, look at whether it needs better placement, tighter replenishment timing, or a quicker markdown decision.

• Connect guest comments to size curves, not just to counts on the rack.
• Watch which categories get replenished in waves, because those are often the ones where demand has been protected.
• Treat a fast sellout as a clue about allocation and forecasting, not only as a service miss.
• Use slow movers to spot where the business needs to protect margin before markdowns spread.
