Summary
Zalando Lounge offered deep discounts but faced high drop-off during the size selection step.
Customers struggled with:
Mixed size formats (EU, UK, US) shown side-by-side.
Illogical ordering and grouping of size options.
No way to quickly find their preferred size.
The size filter became a bottleneck in the conversion funnel—especially during high-traffic sales.
I saw a clear opportunity to:
Reduce friction in the filtering step.
Enable faster product discovery.
Increase order volume without changing pricing, inventory, or promotions.

Users didn’t need another dropdown or modal. They just needed a fast way to jump to their size. Inspired by patterns in ecommerce search behavior, I proposed a low-lift but high-leverage idea: Add a search bar to the size filter.

Partnered with data analysts to track how users interacted with the size filter; most dropped off after scanning just 2–3 screen lengths
Audited top shopping apps and found that most size filters lacked structure, personalization, or searchability—especially on mobile

I implemented a basic search input field at the top of the size filter.
No backend overhaul. Just frontend logic and a clean UI slot.
