ASOS

ASOS was doing visual search back in 2017, years before most retailers took the idea seriously, and its AR fit visualization is still built around a problem specific to fashion: knowing whether something will actually look right on your body, not just whether it's in stock. The scale backs it up — 850,000 product lines from more than 850 brands, a genuinely wide net for fashion discovery rather than the narrow curation most competitors offer. It's built for browsing, not urgency: if you know exactly what you want, a targeted search engine will get you there faster, but if you're looking for something you haven't defined yet, this is where you'll find it.
