iMIHLA Live

Custom E-commerce Platform for South African Streetwear

Visit Website imihla.co.za

Project Overview

iMIHLA is a South African streetwear brand with a clear identity — international in aesthetic, rooted in South Africa. The brand operates on a drop model, releasing limited collections rather than a permanent catalogue. They needed a custom e-commerce platform that matched the brand's sharp visual language and supported this unique release strategy.

The Challenge

  • Off-the-shelf platforms couldn't reflect the brand's distinctive visual identity
  • Required a drop-based release model, not a standard always-available catalogue
  • Needed user accounts, order management, and cart functionality built to spec
  • Brand consistency across every touchpoint — from product pages to checkout

Our Solution

We designed and built a fully custom e-commerce platform including:

  • Custom Storefront: Bespoke design reflecting iMIHLA's black, white, and orange brand language
  • Drop System: Collection-based release architecture — new drops published on schedule, past drops archived
  • User Accounts & Orders: Full account management with order history and tracking
  • Product & Variant Management: Multi-variant product support (colour and style combinations)
  • Cart & Checkout: Streamlined purchase flow with payment integration

Results & Impact
