4. Roman Originals (The Dress)

What happens when your company isn’t even the one behind a viral sensation?

“We woke up one morning and had the world and media coming down upon us,” says Peter Christodoulou, the co-founder of Roman Originals. It started with a wedding photo posted online. A young woman was pictured standing next to a bride, and no one could agree on what color her dress was.

What followed was an international debate dubbed #DressGate.

Christodoulou explained that his company had hoped to sell 200 of the lace-detailed dresses per week, but the UK-based retailer sold 3,000 in just 10 days. Celebrities, global brands, and just about everyone else was tweeting, sharing, and talking about “The Dress.” At its height, the controversy sparked 10,000 tweets per minute.
