Visual search is fast becoming a staple of shopping apps, and ASOS is the latest online retailer to welcome the feature. The UK-based online fashion giant has updated its iOS application with the ability to search for clothes and accessories using photos. Just click the new camera icon in the search box, and you'll be able to either upload a photo you saved on your Camera Roll or to take a picture of something you're looking at in real life. Adjust the image to focus on what item you want to look for, and you're set. I was able to take it for a spin in my little corner of the world here in Asia, so the feature is definitely already available outside the UK.
