The reality of selling fashion online

Size is the silent margin killer.

Across online fashion, around 1 in 4 orders comes back. The single biggest reason: size. Not style. Not quality. Not service. Size.

Each return costs you twice — once in logistics and processing, and once again when the item sits unsold by the time it comes back. The shopper, meanwhile, walks away unsure whether to try you again.

And the orders that hide the most damage are the ones with two sizes "just to be safe." You paid to ship both. You'll pay to take one back.

What we built

One input. Five seconds. A size.

Doreem asks your shopper one thing: which brand fits them well, and what size they wear there. From that single answer, we return their size on your store — with a confidence indicator.

No body data collected. No questions about weight or height. No friction.

The shopper experience

Designed to feel like nothing.

The best size tool is the one your shoppers barely notice. Doreem fits in below your add-to-cart button as a small, optional widget.

  1. 01

    They see a quiet prompt

    "Find your size in 5 seconds"

  2. 02

    They pick a brand they trust

    From a searchable list of well-known fashion labels.

  3. 03

    They enter their usual size in that brand

    XS, S, M, 6, 27 — whatever they know.

  4. 04

    They see their size on your store

    With a confidence indicator if our match is strong.

No login. No account. No measurements. The widget is anonymous by design.

Setup in 15 minutes

You stay in control. Your theme stays untouched.

Doreem installs from the Shopify App Store and integrates as a native theme block. You drag, you drop, you preview, you publish.

Install

One click from the Shopify App Store. Standard OAuth.

Configure

Upload your size chart (CSV, paste, or manual entry). Pick a reference brand whose fit resembles yours.

Publish

Position the widget in your theme editor. See a live preview on your real products.

You can disable it on specific collections, customize colors to match your theme, and pull it down anytime. We are a tool, not a takeover.

What might change for you

Possible gains. No promises.

We're early. We don't have years of client data to wave around. What we do have: a clear understanding of where size-related friction costs you money — and a tool designed to address each of those points.

Here is what Doreem is designed to influence. Whether each of these moves for you depends on your catalog, your shoppers, and your implementation. We're transparent about that.

01

Fewer size-related returns

When shoppers receive a size suggestion they trust, they are less likely to return the item for size reasons. This is the gain we can measure most directly — by comparing your return rate before and after.

02

Fewer "just in case" orders

Some shoppers order two or three sizes hoping one will fit. Every extra unit you ship is logistics you pay for before knowing whether it sells. A confident shopper places a cleaner order.

03

A smoother purchase decision

Size uncertainty is a real friction at checkout. We expect some lift in your conversion rate when shoppers feel sure of their choice — but we'd rather measure it with you than promise it upfront.

04

Less support load on size questions

The "I'm between sizes, can you help?" tickets eat your team's time. Doreem absorbs many of them silently, before they reach your inbox.

We can walk through what each of these might look like in your specific context during a discovery call.

Behind the recommendation

A reference library, built by hand.

We've spent months calibrating a curated library of fashion brands across the spectrum your shoppers actually wear. From accessible everyday labels to mid-premium contemporary, from American minimalism to Scandinavian functional and French elegance — each one mapped to a normalized internal grid.

We don't just compare numbers. Two brands at the same "M" can fit very differently. Our library captures those nuances — slim through the waist, generous through the hip, true to a specific national sizing, garment-measured vs body-measured.

When a shopper tells us what they wear elsewhere, we know what that really means. And we translate it to what it means on your store.

Library expands continuously. If your shoppers' favorite brand isn't there yet, tell us during pilot — we add it.

Early access

We're opening Doreem to a small group of design partners.

Doreem is in private beta. We're working with a handful of fashion brands on Shopify to refine the product before public launch.

Design partners get free access during the pilot, hands-on onboarding, direct input on the roadmap, and locked-in founding pricing when we launch publicly.

In return, we ask you to use the product, share what works and what doesn't, and be patient with us when something breaks.

We'll review your application and get back to you within 48 hours. If we're a fit, we'll set up a 30-minute discovery call. If we're not, we'll tell you honestly and point you to alternatives.

Questions you might have

The honest answers.

Does this slow down my site?

No. The widget is under 20KB gzipped and loads asynchronously. It does not block your page render. We measure this on every release.

Will it break my theme?

No. Doreem integrates as a native Shopify theme block — you drag it into your theme editor exactly where you want it. Your theme files are not modified. If you uninstall, the block disappears cleanly.

What happens if a shopper picks a brand we don't have in your library?

We've built our library to cover the brands your shoppers are most likely to reference. If a shopper picks something we don't have, the widget invites them to consult your standard size chart instead. No bad outcome.

Do I need to upload my size chart? In what format?

Yes — your own size chart is what makes the recommendation accurate for your products. You can upload it as a CSV, paste it from your existing product page, or enter it manually. Most merchants take 5 to 10 minutes.

What about returns I get for reasons other than size?

Doreem only addresses size-related returns. Style, color, fit preference, and quality issues are outside our scope — we won't pretend otherwise.

How is the shopper's data handled?

The widget collects an anonymous session ID and the size inputs the shopper provides. No name, no email, no measurements. We are a data processor under GDPR — a standard DPA is available for European merchants who need it.

What does it cost?

During pilot, Doreem is free. Our public pricing is designed so you only pay when we contribute to a sale, with a monthly cap so costs stay predictable. We'll walk through the details during your discovery call.

Is there a contract or commitment?

No long contract. You install when you want, you uninstall when you want. Doreem must earn its place on your store every month.
