Two people could be the same height and weight, and have a similar body type (like hourglass or apple), but still prefer their clothes to fit differently. How will you differentiate between those who prefer things fitted and those who prefer garments to be looser? "Great question. We account for this in two ways. One: When users share products we ask them to describe how the product fits them. We have designed three fit questions per clothing category that users answer when they add the product. For example, when you add a top you describe the fit across the chest, waist, and length. This allows users to see how the product fits. Two: We adjust a user's recommendations based on the products and sizes they add themselves... For example, when a user adds her favorite H&M top in size small (which fits her tightly), we determine what other brand sizes have been recommended by other people who also like H&M tops in size small. The more products and brands a user adds, the more accurate the recommendations get."
