Nadine West is a fashion subscription box without commitment.
Customers receive an outfit each month and are allowed a short time-frame during which they can send unwanted items back. After the time-frame runs out, they are automatically charged for any items kept.
Data of price/items is fed into an analytics algorithm to predict their (as well as future signups) style month-to-month.
The core of the business model is analytical measurement as opposed to "trends" and the Free-signup, which plays into having a low customer-acquisition cost.
The future involves gamification of the product allowing friends to connect and style each other's surprise outfits.
