Scenario · Custom online store · Sustainable fashion
An online store that tells the product story
and sells better.
A brand with a clear mission and an online store that loses customers at checkout. Product pages that explain materials and supply chain, a cart designed for phones and email automations that bring back people who stopped halfway.
E-commerce scenario — sustainable fashion brand
A brand with a mission.
A checkout to rebuild.
The scenario: a young ethical clothing brand — certified organic cotton, made in Italy, a traceable supply chain that it talks about openly. In a few years it has built a solid Instagram community: loyal followers, good engagement, convinced customers. The problem is the online shop.
The shop runs on a cheap platform with a generic template: product pages with five photos and a flat description, a three-page checkout with repeated fields, no room to tell the supply-chain story, no purchase suggestions. On mobile, cart abandonment is very high — often above 70%. The brand invests in content and community, but the site throws away half the conversions.
The problem is structural, not traffic.
"People arrive at the shop already convinced, they've seen the posts and reels. Then they open the product page and get lost. I don't understand why."
— What brands with a community but a site that doesn't sell typically sayRequirements for an ethical fashion online shop
What was
really needed.
Six areas that come out of a funnel analysis (Hotjar, GA4, session recordings) and talks with the founder. Every problem has to be backed by data, not just impressions.
Supply-chain storytelling built into product pages
Each garment starts from organic cotton, is made by Italian workshops and dyed with natural pigments. That story belongs on the product page — not hidden in an "About" page nobody reads.
Mobile-first, single-step checkout
Most traffic comes from phones. A three-page checkout with repeated fields (email, then address, then payment) offers three chances to leave. Goal: two steps at most in total.
Smart upsell and cross-sell to raise AOV
With an average order value around €65–70 there's room to push it towards €90 with coherent pairings (e.g. top + accessories) and suggestions in the right context, on the product page and in the cart, without being pushy.
Rich-content product pages with editorial photos
The garments are shot by a fashion photographer: beautiful images used badly, compressed thumbnails in a grid. The product page needs to use photos as the main storytelling element, not decoration.
SEO for sustainable fashion — organic traffic
Often the brand doesn't show up for any product search ("organic cotton sweatshirt", "sustainable women's clothing", "ethical fashion"). All traffic comes from social and ads. Building an organic channel means depending less on Meta Ads.
Loyalty and customer program
Most customers buy only once. The brand has everything it needs to build loyalty (quality, mission, community) but no system: no loyalty programme, no post-purchase emails, no reason for a second order.
Technical challenges of a fashion e-commerce
Where the real
problems hide.
A fashion e-commerce on Shopify looks like a standard project. In reality it hides architectural choices that directly affect sales. These are the five main challenges.
Shopify development process for sustainable fashion
How I
organise the work.
Seven to eight weeks in four phases. First you find out where the funnel loses people, then you design the solutions, then you build. No code before the UX choices are validated with real data.
Full analysis with GA4, heatmaps and session recordings. Three main exit points usually emerge: a gallery with no zoom on mobile, a checkout form that's too long, no social proof on the product page. Benchmark against a dozen international sustainable brands.
Complete design system in Figma: palette (e.g. forest green, natural white, terracotta accent), editorial typography (serif for product names, sans for the interface), rules for telling the supply-chain story. An interactive wireframe tested with a few of the brand's real customers before development.
Custom Shopify theme in Liquid: rich product page with a supply-chain section, an always-visible "add to cart" on mobile, a side cart with suggestions, a gallery with zoom. Klaviyo for automated emails, a points programme (e.g. LoyaltyLion) and verified photo reviews (e.g. Judge.me).
A/B test on two product-page variants (supply chain at the top or after the button), catalogue migration with SEO metadata, 301 redirects from old URLs, Google Merchant Center for Shopping, go-live at a low-traffic time. Active monitoring for the following two weeks.
A custom Shopify solution for fashion
How I solve
each problem.
The supply chain as a selling point, not a footnote
The product page is built in sections: at the top, everything needed to buy (photos, name, price, variants, button). Just below, a "How it's made" section with a visual map of the supply chain — certified organic cotton, workshop, natural dye house, Italian tailoring. Each step with place and certification.
This is exactly what the A/B test is for: the supply chain at the top increases time on page, but often reduces purchases; placed after the button it keeps interest without distracting. Position matters as much as content — and the test data decides, not taste.
Photo reviews right after the buy button are one of the most effective ways to increase conversions without touching the price.
Cart drawer + sticky CTA: fewer clicks, more conversions
Without access to Shopify's native checkout (reserved for the Plus plan), everything before it gets optimised: a side cart that opens without leaving the page, with a summary, coherent suggestions and a prominent checkout button. On mobile, a fixed "add to cart" bar stays visible while scrolling the product page.
For payment, Shopify's one-page checkout is switched on with Shop Pay as the main method and autofill for returning customers. Perceived steps drop from three to one. Goal: bringing cart abandonment below 50%.
Klaviyo and LoyaltyLion: from first purchase to returning customer
Four key Klaviyo flows: welcome for new subscribers (3 emails in 7 days with the brand story), post-purchase with a garment-care guide, abandoned cart (two emails, no countdown) and win-back 90 days after the last order.
The points programme is built into the theme: points visible in the header, on every product page and at checkout. They're earned through purchases, photo reviews and shares — in line with the brand's values. A realistic goal: doubling the share of repeat customers within the year.
The abandoned-cart flow is usually the first to pay for itself: it recovers orders that would otherwise be lost, every month, with no manual work.
Shopify e-commerce tech stack
Technologies chosen, not imposed.
Shopify as the platform — the right choice for a B2C brand that has to manage products, stock and payments. A custom Liquid theme, no page builder. Every external app needs a measurable return.
No apps like PageFly or GemPages (Shopify page builders), by choice: they add 200–400 KB of unnecessary JavaScript, slow the site down and create dependency. A custom Liquid theme is faster, easier to maintain and doesn't clash with Shopify updates. Lighthouse goal: 90+ on mobile.
Example goals — fashion e-commerce
What to expect
in the first months.
Example figures, not a client's results: realistic goals for a scenario like this, to be measured with Shopify Analytics, GA4, Klaviyo and the points programme, comparing seasonally similar periods.
"Same ad spend, same traffic — only the site changed." That's the point: when the problem is conversion, you fix the site before buying more traffic.
— The principle behind the whole projectLessons for a fashion e-commerce
What I bring
to every project like this.
These are the points I always keep in mind in fashion and sustainability e-commerce.
Where content sits matters as much as the content. The supply-chain story at the top increases time on page but can reduce purchases. People want to understand what they're buying first, then why. The button before the story, not after — with an A/B test to confirm it.
Subtle suggestions work better than aggressive ones, especially for brands with a community. No cart countdown, no "Forgot something?" pop-up. Editorial pairings ("Often bought together", no fake urgency) raise the average order without annoying anyone.
Shopify Plus isn't always needed to improve checkout. One-page checkout + Shop Pay + a side cart cut abandonment a lot without touching the native checkout. Before spending thousands a month on Plus, optimise everything that comes before it.
A custom theme always beats a page builder for a brand with a strong visual identity. PageFly or GemPages add weight, create style conflicts and make the brand look generic. A tailor-made Liquid theme takes longer to build but it's the only way to make a brand stand out in the sea of Shopify sameness.
Retention beats acquisition, especially for sustainable brands. Getting an existing customer to buy again costs many times less than finding a new one. A points programme and automated emails can double repeat purchases — economically like having twice the customers without raising ad spend.
