What this question tests

Product strategy and design thinking for entering a new adjacent market from an existing social platform.

Users: fashion-conscious Facebook and Instagram users, especially small fashion brands and resellers already active on Marketplace.
Pain points: discovering trustworthy fashion sellers and getting outfit inspiration is fragmented across influencers, ads, and Marketplace.
Prioritize: leverage Facebook's existing strengths, social graph and Marketplace infrastructure, rather than building a new fashion e-commerce platform from scratch.
Solution: a shoppable, social-driven fashion discovery feed connecting Marketplace fashion listings with creator and friend recommendations.
Success metric: fashion category GMV on Marketplace, and conversion rate from social discovery to purchase.
Confirm scope: whether this targets resale and small sellers, or competes with large fashion e-commerce brands directly.

Leverages Facebook's actual existing assets, the social graph and Marketplace, rather than proposing an unrelated standalone app.
Picks a defensible angle, social-driven discovery, where Facebook has a real advantage over pure e-commerce fashion players.
Defines success with a business-relevant metric, fashion category GMV, tied directly to the strategic goal.

Proposing a generic fashion app with no tie to Facebook's existing social graph or Marketplace.
No mention of leveraging existing infrastructure, effectively describing a new company instead.
Vague success metric unrelated to commerce outcomes.

How would you differentiate this from Instagram Shopping, which already exists?
Which seller segment would you prioritize first, resellers or established brands?
