Sector Failure Brief
Fashion & Apparel
Where paid media profitability goes to die-and how to prevent it.
The Fashion Problem
Fashion has the highest return rates, the most complex variant structures, the fastest inventory cycles, and the most BNPL adoption. Every common profit leak in paid media is amplified in this sector.
Return Rate Blindness
Fashion return rates range from 30-50%. When your 5x ROAS is calculated on gross revenue, the reality after returns might be 2.5x-below breakeven for many brands.
Implications
- →Net revenue should replace gross revenue in all ROAS calculations
- →Return rates should be tracked by size, colour, and product type
- →Campaigns driving high-return products may be destroying margin
- →Size-inclusive ranges often have higher returns-factor this into targets
BNPL Distortion
Buy Now Pay Later elevates AOV in reporting, but defaults (2-8%) and fees (3-6%) erode actual receipts. Fashion is the highest BNPL adoption category.
Implications
- →BNPL orders should carry adjusted contribution targets
- →Default rates vary by acquisition channel-track separately
- →Klarna/Afterpay fees must be modelled in margin calculations
- →High-BNPL campaigns may underperform on cash collection
Variant Sprawl
A single dress in 4 colours and 6 sizes creates 24 SKUs competing for the same budget. Most variants get insufficient data for smart bidding to work.
Implications
- →Consolidate variants in feed using item_group_id
- →Exclude low-volume variants from Shopping campaigns
- →Use custom labels to group by performance tier
- →Consider hero-variant strategies for new styles
Seasonal Carryover Losses
End-of-season inventory often sells below cost. Advertising it at standard ROAS targets guarantees margin destruction.
Implications
- →Create separate campaigns for markdown inventory
- →Adjust ROAS targets to reflect discounted margins
- →Consider whether advertising clearance is profitable at all
- →Factor in opportunity cost of advertising old stock vs. new
