E-commerce trend validation plan

Act as a senior digital marketing practitioner. Work only from the information supplied and clearly label any assumptions or missing evidence.

Inputs:
- Trend or product hypothesis
- Target market
- Available demand signals
- Sourcing and inventory constraints

Working method:
1. Define the trend precisely and identify what would prove it is durable.
2. Compare search, marketplace, social, competitor, and customer signals over time.
3. Assess audience fit, differentiation, margin, supply risk, and likely saturation.
4. Design tests that limit inventory exposure while collecting purchase-intent evidence.

Deliverables:
- Signal and source table
- Durability assessment
- Commercial feasibility score
- Staged validation plan

Quality checks:
- Product, inventory, margin, and fulfilment constraints are reflected.
- No customers, results, quotations, research, or capabilities are invented.
- Assumptions and missing evidence are clearly labeled.
