  1. D9 / D10 / D11 — three design iterations in three days

    Aug 27 - Aug 29, 2024

    Three full design iterations shipped in rapid succession. D9 (initial direction), D10 (second iteration), and D11 (third iteration), each developed on its own branch and merged into main via PRs #1, #2, and #3 across Aug 28-29, 2024. First commit on the muscled-clients/Nobile-Guilt repo landed Aug 27, 2024.

    • D9 / D10 / D11

Custom D7 testimonials section finalized with 14 named bilingual reviewer entries, homepage collection switcher (women / men / sale), trust badge row, and TWINT payment messaging all baked into theme settings.

Project overview

What we built

Noble Guilt (nobleguilt.com) is a Swiss DTC fashion and lifestyle clothing brand selling men's and women's apparel. Brand positioning is premium and design-forward: 'Style Meets Elegance,' 'Futuristic fashion, highest quality,' 'Discover Swiss fashion art with innovative designs and excellent workmanship.' The store ships within Switzerland via Swiss Post, DHL, or FedEx and accepts TWINT, the Swiss mobile payment system.

Muscled built the full Shopify theme on a standard Shopify plan (not Plus). Three design iterations (D9, D10, D11) were developed and merged into main via PRs #1, #2, and #3 in a rapid 2-3 day sprint Aug 28-29, 2024, with live-shop refinement commits through Sep 2, 2024 and a single follow-up commit on Jul 21, 2025. 58 commits total. Relationship currently dormant.

The challenge

What was holding them back?

The brand needed a custom theme designed for a German-speaking Swiss audience from day one - not a stock English theme translated after the fact. Three competing design directions had to ship as real merge-able Shopify themes so the client could see the brand running live before committing. Standard Shopify sections couldn't carry the homepage architecture: a featured collection switcher, a brand-story editorial product template, and a custom testimonials section with real Swiss and German customer copy.

  1. 01

    Swiss DTC brand needed a theme designed for a German-speaking audience

    Noble Guilt sells men's and women's fashion in Switzerland. The theme had to handle German-language copy as the primary language, TWINT (the Swiss mobile payment system) messaging, and Swiss Post / DHL / FedEx shipping language — not a stock English theme translated after the fact.

  2. 02

    Three competing design directions needed to be tested before committing

    Before locking the final brand expression, the team wanted to see D9, D10, and D11 running as real Shopify themes rather than as static design comps. Each direction had to be a complete, merge-able theme branch — not a one-page mockup.

  3. 03

    Custom homepage architecture beyond standard Shopify sections

    Noble Guilt's homepage needed a featured collection switcher (women / men / sale tabs), a dedicated brand-story product template for editorial pages, a dedicated collection landing template, and a custom testimonials section with bilingual real-customer copy. Stock Shopify sections couldn't carry the design.

  4. 04

    Real social proof had to read as authentically Swiss

    Generic testimonial widgets read as generic. The brand needed named Swiss and German customer reviews with the original German copy preserved alongside English translations, configurable star ratings, and visible dates — not a Loox-style external widget.

Solutions

What we built to fix it

Each fix maps to a specific lift in the funnel.

  • Custom D7 testimonials section with 14 bilingual named reviewers

    Built sections/d7-custom-testimonials.liquid as a fully custom testimonial component. 14 named real customer reviews baked into theme settings with configurable star ratings, reviewer names, dates, and review text. Bilingual: original German copy alongside English translations. Average rating: 4.78/5.

  • Featured collection switcher + brand-story product template

    Homepage architecture with women / men / sale featured collection switcher. Dedicated product.brand-story.json product template for editorial brand pages, plus collection.collection-landing.json for purpose-built collection landings separate from the standard collection template.

  • Three full theme iterations merged across 2-3 days

    D9, D10, and D11 developed on separate branches and merged into main via PRs #1, #2, and #3 across Aug 28-29, 2024. Each iteration was a complete, working Shopify theme — not a design comp — so the client could see the brand running live before committing to a final direction.

  • Swiss-market polish: TWINT, Swiss Post, multi-language locales

    Scrolling-text announcement bar with TWINT payment notice. Trust badge row with Swiss Post / DHL / FedEx shipping, 30-day refund guarantee, and 5,000+ customer social proof. Multi-language locale files for de, en, fr, es, it, pt-BR, and pt-PT to support multi-market expansion.
