RELEX and Sizeo Partnership to Address Needs in Fashion Planning

Fashion planning often breaks down at the size level. Demand varies by style, color, size, and store. Yet buying and allocation decisions are still frequently made too high up to reflect how apparel actually sells by location. 

That’s why RELEX is working with Sizeo. 

Together, we’re bringing size and pack intelligence into inventory decision-making for fashion, helping teams align plans with real store-level demand. 

By combining RELEX allocation and seasonal planning with Sizeo’s AI-driven size and pack optimization, fashion retailers can: 

🔹 Plan and allocate inventory by style, color, size, and location 

🔹 Define store- and region-specific size ratios based on actual sales patterns 

🔹 Support both bulk and pre-pack strategies, including pack configuration by store 

🔹 Adjust plans automatically when size curves or demand patterns shift 

Once assortments are set, teams can translate those choices into more accurate buying, allocation, replenishment, and markdown decisions by store and size. 

The result is better availability in the sizes customers want, fewer end-of-season leftovers to mark down, and inventory that reflects how each store truly sells. 

Together with Sizeo, we’re supporting fashion teams as they bring size-level planning into day-to-day buying and allocation across physical and digital channels.
