Abstract:

E-commerce has become part of our lives with the number of online shopping transactions rising steadily, while selling clothes online is still challenging greatly due to uncertainty on size and fit selection. Return rate in the textile industry in general is reported between 20% to 40%, which has an enormous financial and environmental impact for retailers and the planet. Many efforts have been made in the past to develop new technology to create accurate 3D humans by mobile phone. However, only knowing the 3D shape of customers is not enough to have an efficient size recommendation tool. How to match the multiple types of personal information, like body shape, preference and potential usage as well as the sizes of the products is less investigated in literature. In this study, an experiment of 175 female participants with different body shapes from XS to 4XL on 6 garment top products was conducted. The collected personal information included not only their body shape, measured by a 3D body scanner and manually par two experimenters, but also their fit preference and practice usage. For each product, they were required to test different sizes to choose their preferred size as it was a purchase in a physical store, and also evaluate a bigger size and a smaller size than the preferred size to check if they would return it in an online shopping scenario. The participants were divided into three groups according to their preference. The first results of the study showed that the fit preference has a significant impact on the size choice. As expected, the data confirmed that independent from the body shape, the participants who declared preferring a loose fit have more chances to choose a bigger size than the theoretical size compared to the group of "adjusted" and "regular" fit. The difference is even more important when it comes to the product with less elasticity, like a jacket. Future research is needed to explore how to integrate the preference information into a size recommendation algorithm, together with body shapes of customers and dimensions of products.
