conversational AI for fashion brands: 5 flows that work.
heysteff is an AI platform for customer support and sales across WhatsApp, Instagram, Messenger, Gmail and Shopify; Steff is the AI agent that runs it. This article isn't a list of promises: it's the detail of five concrete flows you can set up today with the product's real capabilities, applied to a fashion brand.
1. Conversational size guide
Instead of sending the customer to a measurement chart that still doesn't answer their real question, you load your size guide into the agent's trainable knowledge base — including the equivalence between your own sizes and other brands' if you keep one. Steff converses: it asks the minimum necessary (height, usual size, the fit they're looking for) and answers with the recommended size using that guide as the source, not a made-up generic response. If it doesn't have the information for that specific product, it says so and offers to escalate rather than risk a recommendation.
2. Stock lookup by photo
Steff has vision: it can read an image the customer sends over WhatsApp or Instagram. A frequent case in fashion is the customer who sends the photo of a garment — seen in a story, on the street, in another store — and asks if you have it in their size or color. The agent reads the image, matches it against the connected catalog (Shopify, WooCommerce or TiendaNube) and replies with the real stock, not a guess. If the garment isn't yours, it can suggest the closest piece from your own catalog instead of simply saying no.
3. Automated exchanges and returns, with rules
You define your exchange policy once — timeframes, conditions, what's accepted and what isn't — and Steff follows it end to end inside the conversation: it confirms the reason, offers the alternative size or color, generates the return instructions. The agent doesn't improvise policies: if the case falls outside the rules you configured (a damaged garment, a one-off exception), it escalates to your human team via rules and keywords, with the full conversation history already assembled so the person doesn't have to start from zero.
4. Abandoned cart with cross-sell
If you sell on Shopify, automatic abandoned cart recovery fires a message when the customer left products unpaid. What makes a good fashion flow different is that the message doesn't stop at "did you forget something?": the agent can suggest, pulling from the connected catalog itself, a piece that goes with what they already picked — a belt for the pants, a tee for the jacket. heysteff's published benchmark is an average recovery of 4.2x over doing nothing; the cross-sell is what raises the average ticket of that recovery.
5. Drop or seasonal campaign with opt-in
A collection launch or a seasonal sale is built once with the visual automation flow builder and fires on its own to the segment you define, with clear opt-in for whoever receives it. On Pro and Max, outbound campaigns are unlimited, so a new drop doesn't compete for message budget with the abandoned-cart follow-up already running in parallel.
◆ the star flow
The one with the highest direct return is usually the abandoned cart with cross-sell: it doesn't create new demand, it recovers the demand that already existed and makes it a little bigger in the same message.
How it connects and how long it takes to set up
All five flows run on the same connection: for Shopify it's direct OAuth from the heysteff panel, without touching the theme; WooCommerce and TiendaNube are just as native. If your catalog or your size guide lives in another in-house system, the HTTP API tool builder and webhooks connect any source that exposes an endpoint, so the agent always works with real data and not an outdated copy of the inventory.
You don't need to set them all up on day one. Starter is operational the same day with the essentials — size guide and stock lookup —; the rest gets added with the visual flow builder without depending on an external technical team. Pro, with unlimited outbound campaigns, is the natural point to turn on the cross-sell flow and seasonal campaigns in parallel.
