Overview
Online returns surge.
According to the National Retail Federation, 21% of online orders in America, worth $128 billion, were returned in 2022, an 18% increase from 2021. For clothing and shoes specifically, the return rate can reach up to 40%. Online returns cost retailers an average of 20% of the order value, with some reporting even higher percentages.

As online sales continue to rise, the return rate has become a significant issue for businesses, as highlighted by a 2022 study from George Mason University. To address this challenge, retailers are seeking solutions. For example, Walmart recently purchased the virtual fitting room start-up Zeekit.

Not only do returns result in higher costs for the business and customer frustration, but they also have an adverse impact on the environment. According to a report from the Boston Consulting Group, product returns in America are responsible for 15 million tons of carbon emissions each year.

Problem
Selecting the right size for you.
Despite the impressive selection of clothing items available at END., customers are frequently confronted with the challenge of assessing how the clothing will fit their body. While sizing descriptions may provide some guidance, they often fail to account for the diversity of body types. The pervasive issue of incorrect sizing and inadequate fit remains the primary culprit behind the surge in e-commerce clothing returns. Statistics indicate that an estimated 30% of online clothing and shoe orders are subject to returns, leading to a staggering cost of over $30 billion annually for businesses, and generating millions of additional tons of carbon emissions in the process.
Solution
Making a positive impact.
We have devised a Model Fit Guide feature that empowers users to select a model whose body type closely aligns with their own physique. By leveraging this feature, users can preview the clothing item on the selected model and obtain a personalized size recommendation. This approach not only facilitates a streamlined shopping experience but also promotes environmental sustainability by mitigating the frequency of product returns.

Research
Examining the current online shopping environment.
Our aim was to evaluate how users shop and select their clothing size online, as well as to research the business and environmental impact of returns and exchanges on the e-commerce industry. To achieve this objective, we conducted a competitive analysis, user interviews, and secondary research with the following goals in mind:
• Understand the process of how people currently shop for clothing online.
• Understand what people look for when selecting a clothing size online.
• Understand how users determine the optimal size.
• Understand what the customer’s needs/wants are.
• Understand the constraints of the online clothing retailer.
• Understand the business and environmental impacts of returns on the e-commerce retailer.

Research - Competitive Analysis
Striking a delicate balance.
Having conducted an in-depth analysis of various online retailers, ranging from high-end and niche to the largest sportswear companies in the world, we uncovered a number of shared attributes. While some high-end retailers did provide measurements for their models, along with corresponding clothing sizes, these models tended to represent atypical body types that did not reflect the full spectrum of consumer diversity. Conversely, larger retailers offered multiple models and videos for their products, but failed to include detailed sizing information pertaining to these models.

Through this review, we gained insights into the ways in which online retailers are addressing the challenge of providing accurate sizing information to their customers. The analysis underscored the importance of striking a delicate balance between catering to diverse body types and delivering consistent and reliable sizing information, all while ensuring a seamless and satisfying customer experience.

Conclusion
Final thoughts.
The most rewarding aspect of this project was integrating a new feature into a product that I personally have an affinity for. Throughout the research and design stages, it was interesting to see how this feature evolved, especially with the addition of height and weight filters, a confirmation screen, and an environmental impact calculator. These were valuable components that significantly enhanced the feature, and we did not anticipate them at the beginning of the project. Given more time, I would have liked to make the model selection more functional and allow users to see different sizes on the same model.

Overall, the Model Fit Guide has the potential to be a valuable asset for END.'s mobile product, enhancing the shopping experience and potentially reducing the environmental impact of returns. As a designer, this project reinforced the importance of user-centered design and incorporating user feedback throughout the design process. Through continued refinement and iteration, the Model Fit Guide can evolve into an even more valuable and user-friendly feature.
