Children outgrow clothing quickly, making it difficult for parents to keep wardrobes affordable and up to date. Secondhand marketplaces offer a way to reuse clothing, reduce waste, and extend the value of items families no longer need.

Problem

Parents often turn to secondhand platforms to keep up with children’s fast-changing wardrobes, but the experience isn’t always easy to rely on. When resale feels unclear or unpredictable, parents hesitate to follow through, even when motivated to participate.

User Research

Chosen from a broader set of design challenges, six interviews were conducted with parents to understand how they buy and sell children’s clothing secondhand. The research focused on identifying friction points, parent priorities, and concerns related to resale.

Research Goals:

• Identify friction points across the secondhand buying and selling process.

• Understand what parents value when purchasing or reselling children’s clothing.

• Explore concerns related to trust, communication, and transaction security.

Research Findings

Interviews revealed recurring friction across the secondhand clothing resale experience. While parents were motivated to buy and sell, decisions were often delayed or abandoned when the effort required or outcome felt unclear.

Insight:

When buying or selling children’s clothing requires added effort or feels uncertain, parents disengage even when the need is present.

Convenience Breakdowns

The perceived effort required to buy or sell strongly influences whether parents follow through.

Persona

Sarah wants to keep up with her children’s wardrobes without adding complexity to her routine. She balances a demanding career and family life while buying and selling clothing. If the resale process feels time-consuming or difficult to predict, she is likely to disengage.

Insight:

Sarah represents a motivated parent whose participation in resale depends on how efficient and predictable the experience feels.

Problem and How Might We Statements

Parents want to use secondhand platforms to manage their children’s wardrobes, but participation often breaks down when the effort or outcome feels uncertain. When the resale process feels unpredictable, parents hesitate to follow through with transactions.

Competitor Analysis

Spurrty, Markid, and Poshmark were reviewed to understand how parents currently buy and sell children’s clothing secondhand. The analysis focused on how well each platform supports discovery, listing, and transaction clarity.

Insight:

While competitors enable browsing and search, listing and completing transactions often involve friction or unclear expectations, contributing to hesitation and drop-off.

Sketching

Early sketches explored how key details such as item condition, pricing, and transaction options could be surfaced quickly to support confident decisions. Concepts emphasized reducing perceived effort and clarifying what would happen next before a user committed.

Prototype

User Flows

Buyer and seller flows were mapped to make each step of the transaction explicit, from listing to completion. The focus was on removing unnecessary actions and reducing ambiguity so parents could move forward with confidence.

Wireframes refined structure and interactions to reinforce clarity at key decision points. Emphasis was placed on surfacing essential details early and minimizing the effort required to list, evaluate, and complete transactions.

Test

User Testing

Six moderated usability sessions evaluated how parents interacted with the prototype while completing core buying and selling tasks. Testing focused on identifying where confidence increased, where hesitation appeared, and how clearly users understood what would happen next.
