Project Overview

Swap is a mobile application designed to provide users with a convenient and enjoyable shopping experience for second-hand clothing and accessories. The app aims to bridge the gap between thrift stores and potential customers by offering a wide range of affordable and unique items. It serves as a platform for thrift store owners to showcase their inventory and for users to discover, browse, and purchase pre-loved fashion items.

Problem Statement 

The current shopping landscape lacks a convenient and sustainable solution for individuals seeking affordable and environmentally friendly fashion options. Traditional retail stores often offer expensive, fast fashion items that contribute to excessive waste and exploitation of resources. Furthermore, the process of discovering and purchasing second-hand clothing from physical thrift stores can be time-consuming and limited in terms of available choices. Uninformed people are not very open to the idea of thrifting and second hand shopping.

The bigger Problem.

Why Thrift?

  • Thrifting is more sustainable as it reduces the demand for new clothing production, which is resource-intensive and polluting.

  • Thrifting extends the lifespan of clothing, preventing items from ending up in landfills and reducing textile waste.

  • Thrifting can foster a sense of community by connecting like-minded individuals who appreciate sustainable fashion.

  • Thrifted items are often more budget-friendly, allowing individuals to save money and find quality clothing at lower prices.

Why Swap?

  • Swap allows users to browse and shop for second-hand items anytime and anywhere. It eliminates the need to visit physical thrift stores, offering convenience and accessibility to users.

User Interviews

In this phase of the project I conducted User Interviews with 5 participants as a Qualitative Analysis method to understand the user preferences, needs, and pain points related to online thrifting, as well as gather suggestions for improving the app's user experience. Participants were selected based on their interest in sustainable fashion, affordability, and unique style expression.

1. How frequently do you shop for second-hand clothes and how were those experiences for you?

2. What are the most important factors that influence your decision to purchase a pre-owned item like clothing?

3.What are your concerns when you have to use a pre-owned item specifically pre-used clothes?

4.How can you trust someone when you buy used clothes from them?

5. What are your main checkpoints when you buy clothes online?

6. What features would you like to see in a thrift store app?


User Statements

I discard a portion of my wardrobe, once a year. mostly the regular clothes or shoes that are not being used by me so much

I think price is an important factor pre-owned items are generally less expensive than new items

I love shopping for second-hand clothing! I usually go to thrift stores on Instagram.

It can be frustrating when you can't find the item you are looking for

If the item is truly unique in style, design or so I might consider buying such Pre owned item.

The most important factors for me would be the condition of the specific clothing item and how maintained it is.

Affinity Mapping

Affinity mapping exercise was conducted to analyze and organize the data gathered from user interviews, This method allowed for the identification of common themes, patterns, and insights shared by the interview participants

Key Insights from the user interviews

Group 76366.png

People who wanted to get into thrifting were unable to do so due to the unavailability of dedicated online and offline platforms.

The main motivation for gen z to thrift was the affordability of the products and for millennials it was finding unique styles or some fancy product in the store.

The individual considers various factors such as the availability of sizes, pricing, reviews from previous buyers, and delivery time while shopping.

Some users may desire a more personalized shopping experience tailored to their style preferences, body type, and specific fashion needs.

In contradiction to the the thrill of finding the their unique styles, individuals hate the long exhausting and mindless scrolling in search for the right fit.

Social presence, ever-changing fashion trends, affordability and limited wardrobe space are the main drivers for people selling and buying pre-owned clothes.

User Persona

In order to better understand the target audience and their needs, a user persona was created based on the insights gathered from user research. This persona represents a fictional but representative user who embodies the characteristics, goals, and behaviors of the app's intended users.

Review &


Humans can’t hold much information in their short term memory at one time. The product, review and view similar tabs divides the long scroll data from a single unit into three tabs, this optimizes the presentation of information, adheres to Miller's Law by leveraging the limited capacity of human memory, and reduces cognitive load for users.

Test Findings

From the usability tests, the general observation made was that the basic flow and experience of the app for the user was straight forward and made sense.

People were easily able to proceed with placing the order for the product.

People liked the feature of AI generated looks.

Found the application visually appealing.

Thought that there were some hidden tasks and features that were not easy to find.

  • Location Field had very small hit area, difficult to access.

  • The categories card looked unclickable elements due to the low contrast.

  • Location Field is aligned with the top navigation with a bigger hit area.

  • The backdrop color of the categories card is changed for a better contrast.

  • An Ai chatbot FAB is added to the main home screen for better access to the feature.




To sum it up, UX case study for the thrift store app highlights the design process a user-friendly and engaging shopping experience. My main focus was around what users need and want, making sure the app addresses their pain points and offers unique benefits.
Through research and testing, I learned a lot about our users' behaviors and preferences. This helped me create a smooth journey for users, from signing up to finding and buying products.
The app's features, like personalized recommendations, collaborative lookbook creation, and a community feed, make users feel included, inspired, and environmentally conscious.
Throughout this process, I have learned valuable lessons that have shaped my understanding of user experience design and equipped me with valuable skills for future UX projects.
