Sizes don't match between brands. Charts confuse. Returns kill your margins. evow gives every visitor a personal fit-finder in one line of code.

The problem
In fashion e-commerce, 30–40% of orders come back. Most because of size. The cost of returns processing alone eats your margin twice over.
Your size charts don't help. They're brand-specific. Shoppers don't carry a tape measure. Reviews (“fits small”) are subjective. So they order 2 sizes, return 1, and your warehouse burns hours.
Worse: most aren't returns — they're silent abandons. Visitors who don't add to cart because they can't tell if it'll fit.
How it works
No replatforming. No SDK install. No backend changes. Just one script tag.
One line of HTML in your site’s <head>. Works on Shopify, Magento, Salesforce, custom React, anything.
Tell us where to find size attributes in your DOM. We auto-detect 95% of common patterns.
CSS variables for colors, position, typography. Or full white-label — it can look entirely yours.
Visitors see the chip on first visit. They share their size in 30s. Your conversion lifts immediately.
<!-- That's it. The whole integration. -->
