Kids’ Clothing Resale App Design

Project Overview

The goal of this project was to design a user-friendly and trustworthy mobile app that enables parents to easily buy and sell secondhand children’s clothing, promoting sustainability and cost savings through a seamless resale experience.

Target Audience

Busy parents and guardians, including people with impairments, looking for a simple and accessible app to buy and sell kids’ clothes safely and easily.

The Problem/Pain Point

1. Kids outgrow clothes really fast
   Parents end up buying new clothes all the time.
2. Selling used clothes is a hassle
   It takes too much time and effort.
3. Secondhand shopping feels risky
   Buyers worry about stains, sizing, and quality.
4. Parents are busy and stressed
   They need a simple, fast, and easy app.
5. Kids’ clothes create a lot of waste
   Parents want eco-friendly, sustainable options.

Initial Concepts & Design Strategy

My design process started with defining the user needs based on my fictional personas and empathy map. I focused on making the interface simple, intuitive, and accessible. The first concepts were visualized through paper wireframes, where I explored different layout ideas and prioritized user flow.
Feedback from my low-fidelity usability study showed that some features were unclear or hard to find. Based on that, I adjusted button placements, simplified navigation, and added visual hierarchy. These changes were carried into the high-fidelity prototype, which I tested again to confirm the improvements met user expectations.

User Personas

To better understand the goals and frustrations of my users, I created two fictional personas. These personas helped guide my design strategy and kept user needs in focus throughout the process.

Search Conduct

I started with a competitive analysis of similar apps to identify design patterns, usability gaps, and opportunities for improvement. Then, I conducted two rounds of unmoderated remote usability tests using my low and high-fidelity prototypes. I asked friends and family to complete key tasks and share feedback, which helped me uncover pain points, validate design choices, and refine the overall user experience.

Key Challenges

• Designing an easy-to-use app for busy parents and guardians, including those with impairments
• Creating trust in buying and selling secondhand kids’ clothes
• Making sure the app works well on different devices and screen sizes
• Doing the entire design process alone with limited time and resources
• Using fictional personas to understand users and guide the design

Sketches & Wireframes

I started with paper sketches to explore layout ideas and moved into low-fidelity digital wireframes using Figma to refine and structure the design before usability testing.

Result of Any User Testing

I conducted an unmoderated remote usability test with 5 participants. Each person was asked to complete a core task: purchasing a second-hand clothing item. This involved navigating through the main flow — from browsing, selecting an item, and viewing product details, to completing the purchase.

The goal was to evaluate how easily users could:

• Move between screens smoothly
• Understand the flow without getting lost
• Find key actions like “Add to Cart” or “Buy Now”

Final Designs

After iterating on feedback from usability testing, I created a set of polished, high-fidelity screens. These designs reflect a clean user flow, improved navigation, and clearer visual hierarchy. I aimed to create a friendly and intuitive interface for users looking to buy second-hand clothing with ease.
