Tell it your measurements in natural language once. After you've input your measurements, on the sites it supports, a small icon appears in the top right of the page, letting you know the verdict. Hover over it, and a bear tells you if the garment fits, and by how much. It reads the measurements in the site for you, compares them to yours, and includes room for comfort. It never only says yes or no, it explains itself, showing the numbers it used and how it reached a verdict, including if it can't tell. If a page is missing an important measurement, it lets you know which one, and if a shop doesn't publish measurements at all, it says so.
