A unified commerce design foundation built across three consumer brands. One scalable system. Three distinct brand expressions. Designed and implemented in Shopify Plus.

1 The Situation

Three brands. Three separate web sites.

Established brands with real audiences and real revenue, but a fragmented digital stack.

Three separate design languages, three teams, and complex tech stacks. Time to go under a single platform that can grow with the brand.

Every touch, campaign, or content update required duplication — driving speed and increasing cost.

2 The Challenge

No internal commerce system. Everything built ad hoc to launch.

  • Inconsistent experiences within brands and product families
  • High cost for built or custom campaigns and product launches
  • Duplicate engineering work
  • No governance model for documentation

The system did not need fixing. It did not exist.

3 The System Approach

One foundation. Three expressions.

Shared Foundation

  • Design System
  • Grid and Layouts
  • Components
  • Navigation Patterns
  • Access & Standards
  • Design Tokens
  • Shopify Sections

Brand Expression

  • Color Palettes
  • Typography
  • Imagery Direction
  • Icon Patterns
  • Component Styling by Brand

The system powered by Sections. The brands elevated by expression.
