Basically you want to take an established business model and put it online. My first thoughts would be that possibly Buffalo Exchange has a very strong cultural presence which on which its Value Proposition lies, but I am going to try going through your model step by step. My second thought that this business model already exists for women in the form of 99dresses - so maybe have a look at what they do for some more ideas.

I'll go quickly through each blocks of the business model (businessmodelgeneration.com) and try and see whether your business is able to pass each value test. Sorry if it is not thorough, but try using this framework to evaluate businesses. These ideas are from my draft book Theoretical Entrepreneurship (madintelligence.com).

Business Model;

Partner Network: You are going to need partners in the form of consignment (purchase) and fulfilment.

Key Activities: Marketing, Keeping abrest of key trends, fulfilment and storage, relationships with consumers, value setting (how much they buy goods for)

Key Resources: Online presence, storage space, relationships.

Costs: Storage (fixed), Fulfilment (variable), Customer Acquisition (variable), marketing (fixed/variable), product acquisition (fixed/variable).

Revenue: Either subsription based, for per unit based.

Customer Relationships: Online. Little to no contact

Customer Segments: Mass Market "majority...are vintage which is the opposite of direction I would be going in"

Distribution Channels: Online

Value proposition: Online, easy to access designer brands for use in the future (due to delivery).

TESTS.

Value Tests:
1. How do you know the customer has those needs? We can see by competitors and hopefully some statistics that X amount of sales are done, but this is in a local area. If somebody was able to universally control a network of consigment stores and have an online presence we can make profit through economies of scale.

2. Why do you think it is valuable to the customers to solve these needs? Because of need for value, but also a conflicting need to have the best/be the best

3. How might you quantify this value? Through price, through increasing affluence, decreasing willingness to spend.

4. What is the urgency of the need? Very low. Local stores exist in most places that cover this need.

The Execution Test
1. Why do you beleive that your firm is uniquely capable of producing this new offering? Its not. I dont believe there is any special skill you need to run this. Based on the introduction - none.

2. What current capabilities are leveraged by the new offering? None known about.

3. What capabilities are missing? Past experience in fulfilment. Partnerships with fulfilment or with other consignment stores.

4. WHere will these new capabilities come from? Through relationships

5. Which value chain partners do you need to cooperate? Consumers who you buy off. Fulfilment who stocks and issues your goods.

6. Will they be interested? Consumers - possibly an easier way to sell clothes guaranteed (lowering of risk vs. ebay). Fulfilment business - more customers (higher growth).

The Scale Tests
1. Is this need specific to the particular customer, or does it exist across a customer segment? Across a customer segment, all over the world. Its is a large niche market.

2. Specific customer need recurring or is it onetime? It is recurring.
