The case
The interviewer reads this aloud. Try it before you read on.
Our client is Vestiura, a fast-fashion retailer with stores and an online shop in several countries. Its revenue has been flat for two years, and its own customer surveys show more shoppers saying they want to buy fewer new clothes. The CEO is considering a monthly clothing rental subscription: customers pay a fee, receive a set of garments, wear them, and send them back for new ones. Vestiura ran a six-month pilot in one city. The CEO wants to know whether launching this service would be profitable for Vestiura as a whole, and how to position it so it doesn't destroy the existing retail business.
Facts the interviewer gives if you ask
- What did the pilot offer?
- Two plans. An Everyday plan with four everyday pieces at a time (tops, jeans, knitwear) for $60 a month, and an Occasion plan with two formal or occasion pieces at a time (dresses, suits, evening wear) for $80 a month.
- Who signed up?
- Mostly existing Vestiura customers. Before joining, the average subscriber spent $100 a month at Vestiura, in stores and online.
- What margin does Vestiura make on retail sales?
- A 40% contribution margin after the cost of goods, store labor and shipping.
- What would it cost to launch?
- About $40 million: a cleaning and logistics center, the app, and the first stock of rental garments.
- Are there competitors in rental?
- A few small rental start-ups operate in Vestiura's markets, and none is dominant. The team estimates about 2 million potential subscribers across its markets.
- What does the CEO want?
- A profitable new line of business that brings Vestiura back to growth without hurting total company profit.
The solution, step by step
How the case runs in the interview, in 5 steps. Each step has the interviewer's question, the exhibit or data shown, and what a strong answer says.
- 1
Structure the problem
The interviewer asks: “How would you decide whether Vestiura should launch the rental subscription, and how to position it?”
A strong structure
- 1Market: how many people would rent, at what price, and who else offers it
- 2Economics of the service: fee, cost to serve, launch investment
- 3Effect on the core business: retail sales the service replaces
- 4Capabilities and positioning: logistics, cleaning, which garments, brand fit
A strong answer
A market entry structure: the market (size, willingness to pay, competitors), the service's own economics (fee, cost to serve, launch investment, payback), the effect on the core retail business (how much retail spending subscribers stop), and capabilities and positioning (cleaning and reverse logistics, which garments to offer, brand fit). A strong candidate flags early that subscribers are likely existing customers, so the key test is profit net of cannibalization, and that the answer may differ by type of garment.

Read the exhibits
The interviewer asks: “Here is what happened to retail spending in the pilot city, for subscribers on each plan and for similar customers who didn't subscribe. What do you see?”

- Customers who didn't subscribe kept spending about $100 a month.
- Everyday subscribers fell to about $40, so about 60% of their retail spending stopped.
- Occasion subscribers fell only to about $90, about 10%.
A strong answer
Customers who didn't subscribe kept spending about $100 a month. Everyday subscribers dropped to about $40, so they stopped about 60% of their retail spending. Occasion subscribers dropped only to about $90, about 10%. So the Everyday plan replaces purchases Vestiura would otherwise have made, while occasion wear is something these customers rarely bought, so renting it adds to what they spend with Vestiura. The question becomes whether each plan's profit covers the retail profit it replaces.

Do the math
The interviewer asks: “Here are the projected economics of each plan once it is fully rolled out. Taking the lost retail profit into account, what does each plan make per subscriber per month and per year, and what level of cannibalization would make the Everyday plan break even?”
The interviewer adds
- Before joining, a subscriber spent $100 a month at Vestiura at a 40% contribution margin.
Exhibit 2
Projected economics of each rental plan at full rollout
Per subscriber per month, and subscribers expected in year 3. Retail spending lost is the share of a subscriber's store and online spending that stops, from the pilot.
Projected economics of each rental plan at full rollout Plan Monthly fee ($) Cost to serve per month ($) Subscribers in year 3 (k) Retail spending lost (%) Everyday 60 40 200 60 Occasion 80 40 50 10 What to notice
- Everyday makes $20 of subscription profit, Occasion $40.
- Everyday subscribers stop 60% of their retail spending, Occasion only 10%.
- Everyday has four times the subscribers, which makes it look more attractive than it is.
A strong answer
Retail profit per subscriber before joining is $100 times 40%, so $40 a month. Everyday: $60 fee minus $40 cost to serve is $20 of subscription profit, minus 60% of $40, which is $24 of lost retail profit, so minus $4 per subscriber per month. At 200,000 subscribers that is minus $4 times 12 times 200,000, a $9.6 million loss a year on $144 million of revenue. Occasion: $80 minus $40 is $40, minus 10% of $40, $4, so $36 per subscriber per month, and 50,000 subscribers make $21.6 million a year on $48 million of revenue. Break-even cannibalization for Everyday is $20 over $40, 50%, and the pilot shows 60%. The Occasion plan pays back the $40 million launch cost in under two years at full scale.

Brainstorm the options
The interviewer asks: “If Vestiura launches with occasion wear, how should it position and design the service to keep cannibalization low and make it succeed?”
A strong answer
Organized ideas. Offer: occasion and formal pieces only, no basics, a range clearly separate from what stores sell, seasonal events like weddings and parties. Customers: aim marketing at people who don't shop at Vestiura today to grow new spend, and use the sustainability angle the surveys point to. Price and terms: test price points, add a buy-the-piece option for rented items (turns rental into a sale), a pause option. Operations: cleaning and repair quality, damage policy, returns in stores to bring subscribers back through the doors. Guardrails: track each subscriber's retail spending and cap or reshape the plan if cannibalization climbs toward 100% of the $40 margin.

Make the recommendation
The interviewer asks: “The CEO asks for your recommendation. What do you say?”
A strong recommendation
Launch the rental subscription as an occasion and formalwear service only, and keep everyday basics out. Net of the retail profit it replaces, the Occasion plan makes $36 per subscriber per month, about $21.6 million a year at 50,000 subscribers, paying back the $40 million launch in under two years once it reaches full scale. The Everyday plan would bring in $144 million of revenue but lose $9.6 million a year, because subscribers stop 60% of their retail spending, above the 50% break-even. Risks: the pilot was one city for six months, so cannibalization may be different elsewhere, and a fast-fashion brand needs to be credible in occasion wear. Next steps: a second occasion-only pilot in two more cities, track how many subscribers are new to Vestiura, test the price, and design the cleaning and logistics center.

Thanks. So Vestiura's revenue has been flat for two years, its customers say they want to buy fewer new clothes, and it piloted a rental subscription. The CEO wants to know whether the service would be profitable for Vestiura as a whole, and how to position it without hurting the stores. I'll take profitable for the whole company as the test, so the service has to add profit after any sales it takes from the stores. Is that right? Great.
I'd look at four things. First, the market: how many people would rent, at what price, and who else offers it. Second, the economics of the service itself: the fee, the cost to clean and ship garments, the launch investment and the payback. Third, the effect on the core business: how much store and online spending subscribers stop. Fourth, capabilities and positioning: reverse logistics, cleaning, which garments to offer, and whether it fits the brand. My hypothesis is that the third bucket decides this, because subscribers are likely to be existing Vestiura shoppers, and renting the same everyday clothes they used to buy would just move money from one pocket to the other.
Looking at the pilot chart, customers who didn't subscribe kept spending about $100 a month. Everyday subscribers dropped to about $40, so roughly 60% of their spending stopped. Occasion subscribers only dropped to about $90, so about 10%. That makes sense. Someone renting four everyday pieces doesn't need to buy jeans and tops. But formal and occasion wear is something these customers rarely bought from Vestiura anyway, so renting it is mostly new spending.
Now the numbers. Before joining, a subscriber spent $100 a month at a 40% margin, so Vestiura made $40 a month from them. On the Everyday plan, the fee is $60 and the cost to serve is $40, so the plan makes $20. But it costs 60% of $40, which is $24 of retail profit. So net, Vestiura loses $4 per subscriber per month. With 200,000 subscribers, that is $4 times 12 times 200,000, a loss of $9.6 million a year, even though the plan brings in $144 million of revenue. On the Occasion plan, $80 minus $40 is $40, and it only costs 10% of $40, which is $4. So it makes $36 per subscriber per month. With 50,000 subscribers that is $21.6 million a year on $48 million of revenue.
Another way to see it is break-even cannibalization. The Everyday plan makes $20 and a subscriber is worth $40 at retail, so it only works if subscribers stop less than 50% of their spending. The pilot says 60%. The Occasion plan makes $40, the whole retail profit of a subscriber, so it works at almost any cannibalization we could see. And at $21.6 million a year, the $40 million launch pays back in under two years once it reaches full scale.
If Vestiura launches with occasion wear, I'd design it to keep the two businesses apart. The offer should be formal and occasion pieces only, with no basics, and a range that looks different from what is on the store floor. Marketing should aim at people who don't shop at Vestiura today, and use the wish to buy less that the surveys show. I'd add an option to buy a piece you've rented, and let subscribers return items in stores, which brings them back past the racks. And I'd track every subscriber's retail spending as a guardrail, so we can see quickly if cannibalization starts to climb.
So my recommendation is to launch, but only as an occasion and formalwear rental service, and keep everyday basics out. Net of the retail profit it replaces, it makes $36 per subscriber per month, about $21.6 million a year at 50,000 subscribers, and pays back the $40 million launch in under two years once it reaches full scale. The Everyday plan looks bigger, with $144 million of revenue, but it would lose $9.6 million a year, because it replaces 60% of what subscribers used to buy.
The main risks are that the pilot was one city for six months, so cannibalization may be different elsewhere, and that a fast-fashion brand has to earn credibility in occasion wear. Next steps are an occasion-only pilot in two more cities, measuring how many subscribers are new to Vestiura, testing the price, and designing the cleaning and logistics center.
Why this answer works
Judge a new line net of what it replaces
When the new service sells to your own customers, its profit is subscription profit minus the retail profit it takes away. The Everyday plan's $20 turns into a $4 loss.
Bigger revenue can mean a worse business
The Everyday plan brings in three times the revenue of the Occasion plan and loses money. Revenue was the CEO's worry, but profit decides.
Break-even cannibalization is a quick test
Divide the new product's profit per customer by the old one's. Above that share of lost sales, the launch destroys value.
The phrases that do the work
“the service has to add profit after any sales it takes from the stores”
The right test. Setting the test as whole-company profit up front is what makes the cannibalization math matter.
“renting the same everyday clothes they used to buy would just move money from one pocket to the other”
Hypothesis. A plain-language hypothesis that points straight at the case's key issue.
“So net, Vestiura loses $4 per subscriber per month.”
The so-what of the math. Turning $20 of subscription profit into a $4 net loss is the moment the case turns.
“it only works if subscribers stop less than 50% of their spending”
Break-even. A break-even turns a pilot number into a clear yes or no.
Common mistakes on this case
- 1Judging each plan on its own fee minus cost to serve, which makes the Everyday plan look profitable at $20 per subscriber.
- 2Choosing the Everyday plan because it has four times the subscribers and three times the revenue.
- 3Using the full $100 of lost spending instead of the $40 of lost contribution when sizing cannibalization.
- 4Recommending against rental altogether, when the Occasion plan makes $36 per subscriber per month after cannibalization.
- 5Skipping how to position the service, when keeping basics out of the range is what protects the stores.
