Short answer
In fashion, visual content and impulse buys drive the top of the funnel, but high return rates and seasonal swings squeeze the margin. The key is to factor returns into contribution margin, use creative and UGC to create demand, and steer by profit rather than revenue.
01The return rate is the hidden margin-eater
Fashion has one of the highest return rates in e-commerce — double-digit percentages are normal, driven by size and fit. If returns aren't counted in, ROAS, contribution margin and CLTV all look better than they are, and bidding optimises toward a profit that's partly sent back.
So a healthy fashion setup starts by treating expected returns as a variable cost in the contribution margin — and by lowering the return rate at the source: better size guides, true-to-life imagery, and analysis of which items and sizes get returned most.
Sådan virker det
Refunderings- og returraten er andelen af ordrer, der sendes retur eller refunderes. Den æder direkte af dækningsbidraget og forvrider ROAS, hvis den ignoreres — særligt i mode, hvor returrater kan være tocifrede. Den bør regnes med som en variabel omkostning.
02Creative and season drive the top of the funnel
Fashion is a visual, impulse-driven category where Meta and a strong creative flow are often the engine. Fresh angles, UGC and a high tempo of creative testing keep the account fresh, while Google Shopping harvests the demand the brand creates.
Season is the other big factor: collections, sales and weather create peaks and troughs. A CDP and segmentation mean each season doesn't start from zero, but builds on who bought last — and retention via Klaviyo extends the value of each customer beyond the single purchase.
Frequently asked questions
How do I handle high return rates in fashion advertising?+
Count expected returns as a variable cost in contribution margin, so ROAS and bidding reflect reality. Ideally send return-adjusted value to the platforms, and lower the return rate with better size guides and true-to-life product imagery.
Is Meta or Google better for fashion?+
Often both — Meta creates visually driven demand and impulse buys, while Google Shopping harvests the ready-to-buy searches. The balance depends on how well-known the brand is, and should be judged on MER rather than siloed ROAS.
