The fitting-room queue

Nobody can try it on. So it’s the same five questions on a loop.

Fit before the sale, exchanges after it, and the returns in between — the whole apparel queue orbits one thing a shopper can’t do online: try it on. Every ticket is a size, a swap, or a return eating your margin.

  1. 01
    Does this run true to size?

    A pre-purchase fit question — answered from your size chart before the wrong size ever ships, or the cart closes.

    fit / pre-sale
  2. 02
    I need to exchange this for a size up

    The moment to save the sale: an exchange kept in the store instead of a refund walking out the door.

    exchange
  3. 03
    Where is my order?

    The order pulled, tracking checked, an honest ETA — every single time, day and night.

    WISMO
  4. 04
    How do I start a return?

    The return/exchange flow run inside your policy — windows, final-sale, the works — not a link and a shrug.

    returns
  5. 05
    Will this be back in my size?

    A restock question answered honestly from live inventory — never an invented date that breaks trust.

    restock

Most apparel returns are simply the wrong size. Answer fit before the order ships, and save the rest as an exchange — that’s where the margin comes back.

What is AI customer service for fashion & apparel brands?

It answers fit and saves the sale — it doesn’t just process the refund.

AI customer service for fashion & apparel brands is the fitting room a store doesn’t have online. It authenticates the shopper, then works inside your store and returns platform: it answers true-to-size and fit questions from your size chart and product data before the order ships, pulls live tracking for where-is-my-order, and — when something doesn’t fit — turns the return into an exchange or store credit inside your policy instead of defaulting to a refund. It enforces your return windows and final-sale rules, never invents restock dates, and never gives body or health advice. Fit guidance comes from your size chart only; the tough cases still reach a person, with the whole story attached.

The difference shoppers feel

A chatbot pastes the size chart. Lumi fits the shopper.

A chatbot

  • Pastes a size chart and hopes they read it
  • Answers “check the returns page” and closes the chat
  • Refunds by default — the sale walks out the door
  • Can’t tell an exchange from a refund
  • Says “we’ll get back to you” after the drop sells out

Lumi

  • Reads the size chart and recommends the size that fits
  • Turns the return into an exchange and keeps the sale
  • Runs the return/exchange inside your policy and windows
  • Pulls live order & tracking for where-is-my-order
  • Checks live stock before it ever promises a restock

A refund is the sale walking out the door. An exchange is the sale you keep — and the right size answered up front is the return that never happens.

Fit is just the front door

One agent for your whole support & retention motion — not a single-trick bot.

Answering fit is where Lumi starts. Then it keeps going — exchanges, returns, WISMO, restock pings, and the tools you already run.

Every channel a shopper reaches for

Voice, web chat, SMS, email, WhatsApp, Instagram DM — and an on-site AI avatar. The shopper asking about fit under a drop post and the one emailing a return stay one thread.

The fitting room you don’t have

Runs-small, model-height, fabric stretch, true-to-size — Lumi reads your size chart and product data and recommends the size that fits, before the wrong one ships.

Exchange-first, not refund-first

A return request becomes an offered size swap or store credit inside your policy — the sale stays in the store instead of leaving as a refund.

Returns run inside your rules

Return windows, final-sale exclusions, worn/tags-on conditions, exchange vs refund — the policy you approve is enforced on every request, automatically.

A returns desk, not an inbox

Triages, tags, and threads every fit, return, and WISMO ticket. Your team opens to a clean queue and only sees the exceptions worth a person.

Outbound that grows AOV

Back-in-your-size restock pings, exchange follow-ups, review requests, and abandoned-cart recovery on the fit question that stalled the checkout.

Every shopper’s language, any hour

Every shopper, in their language, at any hour — the Sunday-night fit question and the after-drop exchange both get a real answer, not a Monday reply.

Connects to your apparel stack

Store, returns platform, reviews, SMS & CRM — Shopify, Loop Returns, AfterShip, Gorgias, Klaviyo, Yotpo and more, 270+ tools in all, read and written where the work lives.

Save the sale before it’s a refund

A size return is an exchange — until it isn’t.

The window to keep the revenue closes the moment a refund is issued. Lumi acts earlier — answering fit, offering the swap, running the exchange inside your policy — before the sale, the margin, and the shipping all walk.

  1. Fit question, pre-purchase

    The cheapest fix of all. Lumi reads the size chart and recommends the right size — the wrong one never ships.

    sale savable
  2. Wrong size arrives

    Still a saved sale. Lumi offers the swap on the spot before the shopper reaches for a refund.

    sale savable
  3. Return started

    Last call to keep the revenue. Exchange or store credit offered inside your policy while intent is warm.

    sale savable
  4. Refund issued

    Now the sale, the margin, and the shipping are all gone — the expensive path apparel lives on.

    sale lost

No rip-and-replace

Keep the stack you already run — Lumi works on top of it.

Your store, your returns platform, your reviews and SMS — Lumi works inside them, not instead of them. A Shopify partner — and Lumi works inside Loop Returns, AfterShip, Gorgias, Klaviyo, Yotpo, and the rest of your apparel stack. Fit answers, exchanges, and WISMO post straight into the systems your brand already trusts — 270+ tools in all.

Your store, your math

What are size returns costing your margin?

Three sliders. No email gate. This is the margin an exchange-first agent claws back from refunds that should have been swaps.

Margin recovered by saving the sale as an exchange

$2,268/month

$27,216 a year, from roughly 126 wrong-size refunds a month turned into exchanges — assuming ~60% of returns are fit-driven and Lumi saves a conservative 35% of those as an exchange rather than a refund.

And that’s before the pre-purchase fit questions Lumi answers from your size chart, so the wrong size never ships in the first place. Slide it to your own volume, return rate, and handling cost.

Built for a brand you can trust

Hard boundaries for a brand that runs on fit and trust.

Autonomy is worthless if it guesses at bodies or refunds on reflex. These four limits are wired in before the first shopper asks about sizing.

Fit guidance from your size chart only

Lumi recommends sizes from your published size chart and product measurements — never body, weight, or health advice. It helps a shopper pick between a medium and a large; it never comments on their body.

Returns obey the policy, not the pressure

Return windows, final-sale exclusions, worn/tags-on conditions, exchange-first flows — the policy you approve is the outer wall. A shopper who pushes past it gets a graceful hold while your team gets the case. There is no rogue refund path.

It never invents stock or restock dates

Restock and availability answers come from live inventory only. If the size isn’t coming back or the date isn’t known, Lumi says so and offers a back-in-stock alert — it will not promise a drop that isn’t real.

Your brand voice, PCI-safe, in every language

Lumi writes in the tone it learned from your captions and product pages, never asks for card details in a chat, and answers in 70+ languages — the same fitting-room warmth at 3 AM in Lisbon as at noon in LA.

one-message fit answers, at any hour, in the shopper's language

Half our returns were just the wrong size, and my team was refunding them on autopilot. Lumi started answering fit from our size chart before checkout and offering a swap on every return — the exchange rate climbed, the refund pile shrank, and shoppers started thanking us for helping them find their size. I was terrified an AI would talk about customers’ bodies; instead it just reads the chart and keeps the sale.

Objections, welcome

What apparel founders ask before they hand over the fitting room.

How does it answer fit and sizing questions?

From your size chart and product data only. Lumi cites your published measurements, fabric notes, and any runs-small/true-to-size guidance you’ve set, and helps a shopper choose between, say, a medium and a large. It never gives body, weight, or health advice — it reads the chart, not the person. When your data doesn’t contain the answer, it says so rather than guessing.

Can it turn a return into an exchange?

Yes, and that’s the point. When a shopper starts a return, Lumi offers a size swap or store credit first, within the windows and rules you set, so the sale stays in the store. A refund is the fallback when policy allows it, not the default. You decide the exchange-first thresholds, and every action is logged with the reasoning attached.

Does it follow our return policy and windows?

Within the boundaries you draw. Return windows, final-sale exclusions, worn/tags-on conditions, and dollar or category limits are enforced on every request. A shopper who pushes past the policy gets a graceful hold while your team gets the case — there is no rogue refund path, and every exchange or refund is auditable.

Will it invent restock dates to make a sale?

It answers from live inventory only. If the size isn’t in stock, Lumi says so and offers a back-in-your-size alert rather than promising a restock date it can’t verify. It will not invent a drop or a return date to close the conversation.

Which platforms and returns tools does it work with?

We’re a Shopify partner, and Lumi works inside BigCommerce, Wix, and Adobe Commerce, plus returns and reviews platforms like Loop Returns, AfterShip, Narvar, Yotpo, and Okendo, and marketing tools like Klaviyo, Attentive, and Postscript — 270+ integrations in all. It can run alongside your existing help desk instead of replacing it. Bring your stack to a demo and we’ll map what’s supported.

Is it safe with payment and card details?

Never in a chat window. Payment happens on a secure checkout link, and Lumi will not ask a shopper to type card details into a DM, chat box, or email. It’s PCI-safe by design — the card stays with your payment provider, not the conversation.

Can it support shoppers in their own language?

Yes — Lumi converses in 70+ languages and replies in whichever one the shopper opens with, carrying your brand voice across every language instead of flattening into textbook phrasing. A Portuguese fit question gets a Portuguese answer, in your tone. International orders stop being second-class tickets.

When a return needs a human, what does that look like?

Your agent inherits a solved puzzle: the shopper’s order and return history, the fit guidance already given, any photos, and a suggested resolution to accept or override. Serial returners, damaged-in-transit claims, and VIP exceptions route to your team automatically the moment a threshold trips — the shopper never restarts their story from the top.
