How AI augments trend services with quantified, real-time signals merchandisers can act on.
Traditional services like seasonal reports, show coverage, and expert curation remain invaluable for taste and context—especially in luxury and contemporary segments. But merchandisers now operate on shorter cycles with higher volatility, from micro‑trends ignited on TikTok to weather‑driven swings and celebrity spikes.
AI complements—not replaces—traditional methods by ingesting real‑time visual and behavioral signals at scale, spotting pattern shifts early, and quantifying demand confidence with lead times merchandisers can act on. What this looks like in practice: computer vision models classify silhouettes, colors, patterns, and details across millions of social and runway images, while NLP tracks captions, comments, and search trends by region. Time‑series models translate these signals into measurable trend trajectories (emerging, peaking, fading) with suggested buy windows. Vendors such as Heuritech have popularized this approach by quantifying visual signals tied to what people actually wear; see Heuritech and their summary explainer trend forecasting with AI. Meanwhile, The State of Fashion 2024 highlights how gen AI and data‑driven design are reshaping creative workflows; see BoF analysis. For merchandisers, the advantage is tangible: earlier read‑outs on silhouettes (e.g., low‑rise comeback vs. persistent mid‑rise), color families by market, and cross‑category effects (e.g., ballet flat revival lifting pleated skirts). AI augments the buyer’s eye with quantified confidence bands, so pre‑season commitments are calibrated instead of guesswork.
Data without decisions is a dashboard. Close the loop by wiring signals into buy plans and allocation. • Translate signals into buys: Convert AI trend scores into suggested SKU‑level volume ranges by tier (core, fashion, test). Put wide confidence bands on speculative bets and narrow bands on validated trends. • Localize demand by market: Weight signals by region and channel; a color trend peaking in Paris may lag in Dubai. Use social and sell‑through recency to avoid over‑buying late‑stage trends. • Connect merchandising and marketing: When a silhouette is emerging, coordinate creative and paid budgets to accelerate discovery (editorial, visual search, shop‑the‑look). Trend‑led content should echo the attributes AI identified. • Runway‑to‑retail speed: Use AI to spot which runway looks are crossing over to mainstream faster and align drops accordingly. As industry press notes, fashion is increasingly asking AI to predict what will travel from catwalk to closet; see NPR’s coverage of AI‑assisted forecasting during Paris Fashion Week: NPR: AI predicts trends. Traditional houses can keep their creative north star while letting AI filter noise and surface signals worth testing. The goal isn’t to chase every spike; it’s to size buys and allocations with more precision, then learn fast in‑season.
Treat AI forecasting as an operational capability, not a one‑off tool. • Governance and data quality: Establish image and data rights policies; tag training data sources and ensure region‑appropriate usage. Keep explainability by storing attribute‑level rationales (color, silhouette) behind recommendations. • KPIs: Measure forecast hit‑rate by attribute, sell‑through by trend cohort, markdown avoidance, weeks of supply, and speed from signal to buy decision. Track the ROI of test‑and‑replenish loops. • Process: Create a cadence—weekly signal review, monthly buy-plan adjustments, and end‑of‑season attribution. Pair merchants with data partners to interpret signals through a brand lens. • Change management: Start with a capsule (one category, two regions). Compare AI‑informed buys vs. control in matched stores/e‑comm cohorts. Expand only where the uplift is clear and creative direction remains intact.

With tighter feedback loops, merchandisers reduce over‑buys, cut markdowns, and keep the rack aligned with what customers will actually wear.
