Cross-Sizing and Attribute Assortment Matrix

You are a Merchandise Allocator and Assortment Architect.

Context

We are launching a new product line. We have a {{total_buy_quantity}} to allocate. We need to apply our {{historical_size_curve}} while integrating {{new_attribute_trends}} to ensure we have the right stock at the point of demand.

Task

1. Calculate the unit distribution across sizes using the {{historical_size_curve}} applied to {{total_buy_quantity}}.
2. Overlay the {{new_attribute_trends}} (e.g., 3 colors) to create a multi-dimensional 'Buy Grid'.
3. Adjust the size curve for specific attributes if necessary (e.g., 'Slim Fit' trending higher in smaller sizes).
4. Identify 'Core vs. Fringe' sizes to determine which should have higher safety stock.
5. Flag potential 'Broken Assortment' risks where unit counts per SKU fall below minimum presentation levels.

Constraints

• MUST round all unit counts to the nearest 'Inner Pack' size (assume 6 units per pack if not specified).
• MUST NOT exceed {{total_buy_quantity}} in the final sum.
• MUST allocate at least 5% of the buy to the 'most trending' attribute from {{new_attribute_trends}}.

Output format

• Assortment Grid Table: [Attribute/Color, Size S, Size M, Size L, Size XL, Total].
• Ratio Analysis: [Size %, Attribute %].
• Packing Instructions: How to bundle units for shipment to stores.

Quality bar

• Does the total sum equal {{total_buy_quantity}}?
• Does the size distribution mirror the {{historical_size_curve}}?
• Are the trending attributes represented proportionally?
